Rolls-Royce Holdings plc is a British multinational aerospace and defence company incorporated in February 2011. The company owns Rolls-Royce, a business established in 1904 which today designs, manufactures and distributes power systems for aviation and other industries. Rolls-Royce is the world's second-largest maker of aircraft engines [3] (after CFM International) [4] and has major businesses in the marine propulsion and energy sectors.
Rolls-Royce was the world's 16th largest defence contractor in 2018 when measured by defence revenues. [5] The company is also the world's fourth largest commercial aircraft engine manufacturer, with a 12% market share as of 2020 [update] . [6]
Rolls-Royce Holdings plc is listed on the London Stock Exchange, where it is a constituent of the FTSE 100 Index. At the close of London trading on 28 August 2019, the company had a market capitalisation of £4.656bn, the 85th-largest of any company with a primary listing on the London Stock Exchange. [7]
The company's registered office is at Kings Place, near Kings Cross in London. [8]
Rolls-Royce grew from the engineering business of Henry Royce, which was established in 1884 and ten years later began to manufacture dynamos and electric cranes. Charles Rolls established a separate business with Royce in 1904 because Royce had developed a range of cars which Rolls wanted to sell. A corporate owner was incorporated in 1906 with the name Rolls-Royce Limited. [9]
In 1971 the same company, Rolls-Royce Limited, entered voluntary liquidation because it was unable to meet its financial obligations. It remains in existence today, still in liquidation. Its business and assets were bought by the government using a company created for the purpose named Rolls-Royce (1971) Limited. Rolls-Royce Motors was separated out in 1973. Rolls-Royce (1971) Limited currently carries on the business under the name Rolls-Royce plc. [10]
Rolls-Royce plc returned to the stock market in 1987 under the government of Margaret Thatcher. In 2003 ownership of Rolls-Royce plc was passed to Rolls-Royce Group plc. In the same way, Rolls-Royce Group plc passed ownership on 23 May 2011 to Rolls-Royce Holdings plc. [11] Throughout these corporate changes Rolls-Royce plc has remained the principal trading company. [11] [nb 1]
The 1980s saw the introduction of a policy to offer an engine fitment on a much wider range of civil aircraft types, with the company's engines now powering 17 different airliners (and their variants) compared to General Electric's 14 and Pratt & Whitney's 10. [12]
The civil engines business represents the company's main area of growth. Between 2010 and 2018, Rolls-Royce invested £11 billion in facilities and R&D and launched six new civil engines including the Trent XWB and the Pearl 15 for the business aviation market. It secured orders for 2,700 engines for wide-body aircraft and business jets. It expects to produce over 600 wide-body engines a year and should power over half of the world's wide-body fleet within a few years, up from 22% a decade before. [13]
In 2023, Rolls-Royce entered into an agreement for $3.52 million of funding with the UK Space Agency for the creation of a nuclear reactor on the moon. The project is intended to provide power for space missions. [14]
In 2014 and 2015, Rolls-Royce issued at least four profit warnings due to US defence cuts, a downturn in the offshore oil and gas market and its civil aerospace business, the company initiated job cuts of over 3,000 in response. [15] [16] [17] [18] Rolls-Royce had been selling many of its aero-engines in combination with long-term service contracts. Even though the company booked profits in part with the delivery of the engine, actual payments only came in over time. Between 2003 and 2015, it sold a majority of its engines with these “TotalCare” contracts. [19] The company announced it would no longer be able to move its revenues forward from its long-term service contracts to compensate for its contracts being unprofitable in the early stages after the introduction of IFRS 15 in 2018 and its profits for 2015 would have been £900m lower than the £1.4bn it reported if it had followed the new accounting standard. [20] [21] [22]
In February 2017 Rolls-Royce posted its largest ever pre-tax loss of £4.6 billion; This included a £4.4 billion writedown on financial hedges that the company uses to protect itself against currency fluctuations, and a £671 million penalty to settle bribery and corruption charges with the Serious Fraud Office (SFO), the US Department of Justice, and Brazilian authorities. [23]
On 14 June 2018 the company announced a restructuring of the business to create three simpler decentralised units (civil aerospace, defence and power systems), to rationalise back office functions and to remove middle management functions. The cost savings should amount to £400 million per year by 2020, with an up-front restructuring cost of £500 million. Some 4,600 people [24] are likely to leave the business out of 55,000 employed worldwide, 3,000 job losses from the UK and the rest from elsewhere in the world [25] (15,700 of the employees work in Derby and 10,300 work elsewhere in the United Kingdom). [26] [27]
In August 2018 Rolls-Royce announced it was taking a charge of £554 million to cover faults with some Trent 1000 engines on Boeing 787 Dreamliners. Rather than going thousands of hours between inspections, the faults with turbine blades mean the engines currently require inspection every 300 hours of flight. In the same announcement Rolls-Royce said it would spend £450m fixing faults on the Trent 1000 in 2018, £450m in 2019 and £350m in 2020, with the work complete by 2022. [28]
In May 2020, the company announced its intention to cut 20% of its workforce (approximately 9,000 staff) worldwide as a result of the COVID-19 pandemic. [29] [30] Around 3,000 job losses were expected in the UK, half of them in Derby. [31]
In February 2021, Rolls-Royce started talks concerning an operational shutdown of its civil aerospace unit that might last for two weeks due to the impact of Covid-19 and its restrictions. [32]
Rolls-Royce announced, in October 2023, that it would cut 2,500 jobs, or 6 per cent of its total workforce. [33]
Rolls-Royce's £90 million test bed 80 is the largest of its kind, sized for engines of up to 140,000 lbf (620 kN) of thrust. [38] Design started in 2017, construction began in 2018 and it should be commissioned by mid-2020. The 80,730 sq ft (7,500 m2) facility is 426.5 ft (130.0 m) long, has a 95 ft (29 m) tall intake tower and a 123 ft (37 m) tall exhaust stack. Built from 3,450 tons of steel and 27,000 m3 (950,000 cu ft) of concrete, it has a 49 by 49 ft (15 by 15 m) tall and wide enclosed space and it can handle a 66 tons engine including its carrier. [38] The company completed its first engine run on the new test bed in July 2024. [39]
X-ray imaging allows to visualize the position of seals and clearances in real time while an engine is running. While it was retrofitted on Rolls' test bed 57, test bed 80 is the first to be purpose-designed for industrial radiography. To protect from external X-ray, 30 cm (11.8 in.) of lead, double walls are up to 8.9 ft. (2.7 m) thick (a 5.6-ft. interior wall and 3.3-ft. exterior wall) and provide acoustic insulation. Canadian prime contractor MDS Aero Support is responsible for design and management, test systems supply, engine adapters, support systems and data acquisition and control while construction is done by Buckingham Group Contracting. [38]
In 1988, Rolls-Royce acquired Northern Engineering Industries (NEI), based in the North East of England, a group of heavy engineering companies mainly associated with electrical generation and power management. The group included Clarke Chapman (cranes), Reyrolle (now part of Siemens) and Parsons (now part of Siemens steam turbines). The company was renamed Rolls-Royce Industrial Power Group. It was sold off piecemeal over the next decade as the company re-focused on its core aero-engine operations following the recession of the early 1990s. [40]
On 21 November 1994, Rolls-Royce announced its intention to acquire the Allison Engine Company, an American manufacturer of gas turbines and components for aviation, industrial and marine engines. [41] The two companies had a technical association dating back to the Second World War. Rolls-Royce had previously tried to buy the company when General Motors sold it in 1993, but GM opted for a management buyout instead for $370 million. Owing to Allison's involvement in classified and export restricted technology, the 1994 acquisition was subject to investigation to determine the national security implications. [42] On 27 March 1995, the US Department of Defense announced that the "deal between Allison Engine Co. and Rolls-Royce does not endanger national security." [43] Rolls-Royce was, however, obliged to set up a proxy board to manage Allison and had also to set up a separate company, Allison Advanced Development Company, Inc., to manage classified programmes "that involve leading-edge technologies" such as the Joint Strike Fighter programme. [43] In 2000, this restriction was replaced by a more flexible Special Security Arrangement. [44] In 2001, Rolls-Royce and its LiftSystem was among the group that won the JSF contract for the F-35. [45]
The Allison acquisition, at $525 million (equivalent to £328 million), [41] brought four new engine types into the Rolls-Royce civil engine portfolio on seven platforms and several light aircraft applications. Allison is now known as Rolls-Royce Corporation, part of Rolls-Royce North America. [46]
In 1999 Rolls-Royce acquired Vickers plc for its marine businesses. [47] The portion retained is now Vinters Engineering Limited. Rolls-Royce sold Vickers Defence Systems (the other major Vickers area of business) to Alvis plc in 2002. [48]
Rolls-Royce has established a leading position in the corporate and regional airline sector through the development of the Tay engine, the Allison acquisition and the consolidation of the BMW Rolls-Royce joint venture. In 1999, BMW Rolls-Royce was renamed Rolls-Royce Deutschland and became a 100% owned subsidiary of Rolls-Royce plc. [49]
Optimized Systems and Solutions Limited (formerly known as Data Systems & Solutions) was founded in 1999 as a joint venture between Rolls-Royce plc and Science Applications International Corporation (SAIC). In early 2006, SAIC exited the joint venture agreement, making Rolls-Royce plc the sole owner. [50]
In March 2011, Rolls-Royce and Daimler AG launched a $4.2 billion public tender offer for 100 per cent of the share capital of Tognum AG, the owner of MTU Friedrichshafen – a leading high-speed industrial and marine diesel engine manufacturer, which was completed using a 50:50 joint venture company. [51] Rolls-Royce and Daimler AG intend that the joint venture company, which also now incorporates Rolls-Royce's existing Bergen engine business, is listed on the Frankfurt Stock Exchange. [51]
Following the acquisition of Goodrich by United Technologies Corporation in July 2012, Rolls-Royce announced it would purchase Goodrich's 50% share of Aero Engine Controls to become wholly owned by Rolls-Royce. [52]
At the June 2019 Paris Air Show, Rolls-Royce announced its acquisition of Siemens' electric propulsion branch (while they are partners on the E-Fan X demonstrator), to be completed in late 2019, employing 180 in Germany and Hungary. [53]
In May 2014, Rolls-Royce sold its energy gas turbine and compressor business to Siemens for £785 million. [54]
In July 2018, Rolls-Royce sold its commercial marine business to Kongsberg for £500 million. [55]
In September 2019, Rolls-Royce agreed to sell its civil nuclear services businesses in the U.S., Canada, Mondragon France, and Gateshead UK to the Westinghouse Electric Company for an undisclosed sum. These businesses had a revenue of $70 million and about 500 employees in 2018. Rolls-Royce is keeping its nuclear new build and small modular reactor (SMR) business in the UK. [56] In November 2020, the company announced plans to build up to 16 Rolls-Royce SMR nuclear plants across the UK, continuing its nuclear division operations. [57] In December 2020 Rolls-Royce announced it would sell other foreign parts of its civil nuclear instrumentation and control business to Framatome as part of its post-COVID recovery plan, completing the deal involving over 550 employees in November 2021. [58] [59]
In 1996, Rolls-Royce and Airbus signed a memorandum of understanding, specifying the Trent 900 as the engine of choice for the then A3XX, now the Airbus A380. [60] However, the Engine Alliance GP7000 would ultimately also be offered as an option on the A380. [61]
In October 2006, Rolls-Royce suspended production of its Trent 900 engine because of delays by Airbus on the delivery of the A380 superjumbo. Rolls-Royce announced in October 2007 that production of the Trent 900 had been restarted after a twelve-month suspension caused by delays to the A380. [62]
In 2011, Rolls-Royce faced scrutiny after high profile incidents involving the Trent 900. One of the engines suffered a partial power loss during a Qantas flight in February 2011. This followed an incident in November 2010 in which an engine disintegrated in flight causing Qantas Flight 32 to make an emergency landing in Singapore. [63] The aircraft was extensively damaged and the airline grounded its fleet of A380s. The problem was traced to a fatigue crack in an oil pipe requiring the replacement of some engines and modifications to the design. [64] Trent-powered A380s operated by Lufthansa and Singapore Airlines were also affected. Qantas gradually returned its A380s to service over several months. In June 2011 the airline announced it had agreed to compensation of AU$95m (US$100m) from Rolls-Royce. [65]
On 17 April 2015, it was announced that Rolls-Royce had received its largest order to date worth £6.1bn ($9.2bn) to supply engines for 50 Emirates A380 planes. [66] [67] [68]
On 6 April 2004, Boeing announced that it had selected both Rolls-Royce and General Electric to power its new 787. Rolls-Royce submitted the Trent 1000, a further development of that series. [69]
In July 2006, Rolls-Royce reached an agreement to supply a new version of the Trent 1000 for the revised Airbus A350XWB jetliner. As of July 2015, over 1,500 engines of this type have been supplied to 40 customers. [70]
On the military side, Rolls-Royce, in co-operation with other European manufacturers, has been a major contractor for the RB199 which in several variants powers the Panavia Tornado, and also for the EJ200 engine for the Eurofighter Typhoon. Rolls-Royce has matured the Rolls-Royce LiftSystem invented by Lockheed Martin for the F-35 Lightning II to production level; The F-35 is planned to be produced in significant numbers. [71]
At the 2005 Paris Air Show, Rolls-Royce secured in excess of $1 billion worth of orders. The firm received $800m worth of orders from Air China to supply its 20 Airbus A330 jets. [72]
On 18 June 2007, Rolls-Royce announced at the 2007 Paris Air Show that it had signed a large contract with Qatar Airways for the Trent XWB to power 80 A350s on order from Airbus worth $5.6 billion at list prices. [73]
On 11 November 2007, Rolls-Royce announced at the Dubai Airshow that it had signed its largest ever contract with Emirates for Trent XWBs to power 50 A350-900 and 20 A350-1000 aircraft with 50 option rights. Due to be delivered from 2014, the order is potentially worth up to 8.4 billion US Dollars at list prices. [74]
On 20 November 2007, Rolls-Royce announced plans to build its first Asian aero engine facility in the Seletar Aerospace Park, Singapore. [75] The $562m (£355m) plant complements its existing facility at Derby by concentrating on the assembly and testing of large civil engines, including Trent 1000 and Trent XWB. Productivity will be higher than at Derby, as the plant is fully integrated, as opposed to manufacturing occurring across five sites in the UK: a Trent 900 will take only 14 days to manufacture, as opposed to 20 in the UK. Originally expected to provide employment for 330 people, [76] by the start of production in 2012, 1,600 employees were based in Singapore. [77]
In May 2012, Rolls-Royce Marine Power Operations won a Ministry of Defence contract worth more than £400 million for the integration of the reactor design, the PWR3, for UK's next generation nuclear-armed submarines. [78] In March 2023, Rolls-Royce announced that Rolls-Royce Submarines Limited will provide nuclear reactors for the SSN-AUKUS class of submarines for both the Royal Navy and Royal Australian Navy. [79] To support the SSN-AUKUS programme, Rolls-Royce announced it would double the size of the Rolls-Royce Submarines LTD site in Raynesway, Derby creating 1,170 jobs in the process [80]
Rolls-Royce has been accused numerous times of corrupt practices and bribery.
In 2014, facing allegations of bribery in the aftermath of the Sudhir Choudhrie affair, Rolls-Royce offered to return money to the Indian government. [81] The Serious Fraud Office (SFO) also investigated allegations of bribery in Indonesia and China. [82]
In February 2015 Rolls-Royce was accused of bribing an employee of Brazil's state-controlled oil company to win a $100 million contract to provide gas turbines for oil platforms. [83]
In October 2016 a joint Guardian and BBC investigation alleged widespread corruption by Rolls-Royce through middlemen in foreign countries including Brazil, India, China, Indonesia, South Africa, Angola, Iraq, Iran, Kazakhstan, Azerbaijan, Nigeria and Saudi Arabia. Rolls-Royce became subject to a major SFO investigation. [84]
In 2013 media reported allegations from two American ex-employees that thousands of the company's new jet engines were assembled with used parts. [85]
In January 2017 Rolls-Royce came to an agreement with the SFO to pay £671 million under a deferred prosecution agreement to avoid prosecution for bribery to obtain export contracts. [86] [87] As part of this agreement, a $170 million fine was paid to US authorities to end a bribery investigation, [88] and $25 million to the Brazilian authorities. [86]
Subsequent to the settlement, Private Eye reported that some of Rolls-Royce's contracts under the scope of the SFO investigation had been supported by the British government's UK Export Finance department, using taxpayers' money. The government department underwrote multimillion-pound liabilities under Rolls-Royce contracts secured with the help of bribes and "facilitation" commissions. It has also been highlighted in the press that Rolls-Royce's auditor since 1995, KPMG, had failed to identify any corrupt practices throughout the 1990s and 2000s. This is notable considering judge Brian Leveson's statement that Rolls-Royce's offending was "multi-jurisdictional, numerous", "persistent and spanned from 1989 until 2013", and it "involved substantial funds being made available to fund bribe payments". [89]
As of August 2021 [update] the board of directors consists of: [90]
Rolls-Royce's aerospace business makes commercial and military gas turbine engines for military, civil, and corporate aircraft customers worldwide. In the United States, the company makes engines for regional and corporate jets, helicopters, and turboprop aircraft. Rolls-Royce also constructs and installs power generation systems. Its core gas turbine technology has created one of the broadest product ranges of aero-engines in the world, with 50,000 engines in service with 500 airlines, 2,400 corporate and utility operators and more than 100 armed forces, powering both fixed- and rotary-wing aircraft. Rolls-Royce Marine Power Operations (a subsidiary company) manufactures and tests nuclear reactors for Royal Naval submarines. [91]
In 2019, Rolls-Royce delivered 510 Trent powerplants, while 5,029 large engines were installed, including 32% Trent 700s. [92] For business jets, research and development in the market niches is a $2 billion annual investment, for a predicted market of 8,500 to 9,000 aircraft over the 2020 decade. [93]
Pratt & Whitney is an American aerospace manufacturer with global service operations. It is a subsidiary of RTX Corporation. Pratt & Whitney's aircraft engines are widely used in both civil aviation and military aviation. Its headquarters are in East Hartford, Connecticut. The company is the world's second largest commercial aircraft engine manufacturer, with a 35% market share as of 2020. In addition to aircraft engines, Pratt & Whitney manufactures gas turbine engines for industrial use, marine propulsion, and power generation. In 2017, the company reported that it supported more than 11,000 customers in 180 countries around the world.
The Airbus A380 is a very large wide-body airliner, developed and produced by Airbus. It is the world's largest passenger airliner and the only full-length double-deck jet airliner. Airbus studies started in 1988, and the project was announced in 1990 to challenge the dominance of the Boeing 747 in the long-haul market. The then-designated A3XX project was presented in 1994; Airbus launched the €9.5–billion ($10.7–billion) A380 programme on 19 December 2000. The first prototype was unveiled in Toulouse on 18 January 2005, with its first flight on 27 April 2005. It then obtained its type certificate from the European Aviation Safety Agency (EASA) and the US Federal Aviation Administration (FAA) on 12 December 2006.
The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce. The engines are capable of generating 41,030 to 59,450 lbf of thrust. The RB211 engine was the first production three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader.
The Rolls-Royce Trent is a family of high-bypass turbofans produced by Rolls-Royce. It continues the three spool architecture of the RB211 with a maximum thrust ranging from 61,900 to 97,000 lbf . Launched as the RB-211-524L in June 1988, the prototype first ran in August 1990. Its first variant is the Trent 700 introduced on the Airbus A330 in March 1995, then the Trent 800 for the Boeing 777 (1996), the Trent 500 for the A340 (2002), the Trent 900 for the A380 (2007), the Trent 1000 for the Boeing 787 (2011), the Trent XWB for the A350 (2015), and the Trent 7000 for the A330neo (2018). It has also marine and industrial variants like the RR MT30.
The Engine Alliance GP7000 is a turbofan jet engine manufactured by Engine Alliance, a joint venture between General Electric and Pratt & Whitney. It is one of the powerplant options available for the Airbus A380, along with the Rolls-Royce Trent 900.
The Airbus A350 is a long-range, wide-body twin-engine airliner developed and produced by Airbus. The initial A350 design proposed in 2004, in response to the Boeing 787 Dreamliner, would have been a development of the Airbus A330 with composite wings and new engines. Due to inadequate market support, Airbus switched in 2006 to a clean-sheet "XWB" design, powered by two Rolls-Royce Trent XWB high bypass turbofan engines. The prototype first flew on 14 June 2013 from Toulouse, France. Type certification from the European Aviation Safety Agency (EASA) was obtained in September 2014, followed by certification from the Federal Aviation Administration (FAA) two months later.
The Rolls-Royce Trent 500 is a high-bypass turbofan produced by Rolls-Royce to power the larger A340-500/600 variants. It was selected in June 1997, first ran in May 1999, first flew in June 2000, and achieved certification on 15 December 2000. It entered service in July 2002 and 524 engines were delivered on-wing until the A340 production ended in 2012.
The Rolls-Royce Trent 700 is a high-bypass turbofan aircraft engine produced by Rolls-Royce plc to power the Airbus A330. Rolls-Royce was studying a RB211 development for the A330 at its launch in June 1987. It was first selected by Cathay Pacific in April 1989, first ran in summer 1992, was certified in January 1994 and was put into service on 24 March 1995. Keeping the characteristic three-shaft architecture of the RB211, it is the first variant of the Trent family. With its 97.4 in (247 cm) fan for a 5:1 bypass ratio, it produces 300.3 to 316.3 kN of thrust and reaches an overall pressure ratio of 36:1. It competes with the General Electric CF6-80E1 and the PW4000 to power the A330.
The Rolls-Royce Trent 800 is a high-bypass turbofan produced by Rolls-Royce plc, one of the engine options for the early Boeing 777 variants. Launched in September 1991, it first ran in September 1993, was granted EASA certification on 27 January 1995, and entered service in 1996. It reached a 40% market share, ahead of the competing PW4000 and GE90, and the last Trent 800-powered 777 was delivered in 2010. The Trent 800 has the Trent family three shaft architecture, with a 280 cm (110 in) fan. With a 6.4:1 bypass ratio and an overall pressure ratio reaching 40.7:1, it generates up to 413.4 kN of thrust.
The Rolls-Royce Trent 900 is a high-bypass turbofan produced by Rolls-Royce plc to power the Airbus A380, competing with the Engine Alliance GP7000. Initially proposed for the Boeing 747-500/600X in July 1996, this first application was later abandoned but it was offered for the A3XX, launched as the A380 in December 2000. It first ran on 18 March 2003, made its maiden flight on 17 May 2004 on an A340 testbed, and was certified by the EASA on 29 October 2004. Producing up to 374 kN (84,000 lbf), the Trent 900 has the three shaft architecture of the Rolls-Royce Trent family with a 2.95 m (116 in) fan. It has a 8.5–8.7:1 bypass ratio and a 37–39:1 overall pressure ratio.

Qantas Flight 32 was a regularly scheduled passenger flight from London to Sydney via Singapore. On 4 November 2010, the aircraft operating the route, an Airbus A380, suffered an uncontained failure in one of its four Rolls-Royce Trent 900 engines. The failure occurred over the Riau Islands, Indonesia, four minutes after takeoff from Singapore Changi Airport. After holding for almost two hours to assess the situation, the aircraft made a successful emergency landing at Changi. No injuries occurred to the passengers, crew, or people on the ground, despite debris from the aircraft falling onto houses in Batam.

The company produces engine control software, electronic engine controls (EEC), fuel metering units (FMU), fuel pumps and engine actuators for a large number of common commercial and military aircraft. Together these parts comprise the control system for a jet engine, responsible for delivering the correct amount of fuel and maintaining engine safety.
The Rolls-Royce Trent XWB is a high-bypass turbofan produced by Rolls-Royce Holdings. In July 2006, the Trent XWB was selected to power exclusively the Airbus A350. The first engine was run on 14 June 2010, it first flew on an A380 testbed on 18 February 2012, it was certified in early 2013, and it first flew on an A350 on 14 June 2013. It had its first in-flight shutdown on 11 September 2018 as the fleet accumulated 2.2 million flight hours. It keeps the characteristic three-shaft layout of the Rolls-Royce Trent, with a 3.00 m (118 in) fan, an IP and HP spool. The 84,200–97,000 lbf (375–431 kN) engine has a 9.6:1 bypass ratio and a 50:1 pressure ratio. It is the most powerful member of the Trent family.
The Rolls-Royce Trent 7000 is a high-bypass turbofan engine produced by Rolls-Royce, an iteration of the Trent family powering exclusively the Airbus A330neo.
