UUV TALISMAN of BAE SystemUUV TALISMAN model (BAE System)
The Talisman UUV is a fully autonomous unmanned mini-sub designed and made by BAE Systems. It has the capability to perform shoreline reconnaissance when the risks may be deemed too high, or conditions unsuitable, for human operators.
The Talisman system comprises a vehicle and remote control console. The vehicle can be re-programmed in mid-mission by satellite and features a carbon fibrehull giving it a stealth-like profile and low observability. Talisman can carry a wide variety of payloads, such as image capture, environmental sensors or mine counter measures.
Programme history
The Talisman programme was launched in late 2004, and was developed and managed by BAE Systems Underwater Systems and went from paper to initial trials in less than a year.
Talisman has undergone a series of trials in the Irish Sea, with 100 per cent success rate. During further trials in late 2006, Talisman has become the first UUV to successfully fire and control weapons at sea during trials off the South Coast of England.[citation needed]
The first remote sea launch of the Archerfishmine disposal system from Talisman was successfully completed during the trials.[citation needed] The mine neutraliser then acquired Talisman and subsequently simulated target eradication. In another deployment, also from the Talisman UUV, Archerfish successfully identified and acquired BAE Systems' versatile exercise mine system (VEMS).[citation needed]
The vehicle
The Talisman vehicle is based on an innovatively shaped carbon fibre composite hull, with internal pressure vessels containing the electronics systems and payload. The stealthy hull design was based on BAE Systems’ aircraft technology. The vehicle weighs 1800kg, is approximately 4.5m long by 2.5m wide, can dive to 300m and has a top speed of 5 knots (9 km/h).[citation needed]
It is fitted with vectorable thruster pods, which allow it to manoeuvre very accurately in difficult conditions, including strong currents, and over an extended period of time: the Talisman can be deployed 50 miles offshore and remain in operation for 24 hours.[citation needed] The precise handling in all directions comes from six thrusters, two at the front, and four at the back in two pairs. A rotary actuator is used to vector each pair of thrusters and to operate the hydroplanes.[citation needed]
Talisman has been designed with a software architecture, which allows easy and rapid re-configuration of the mission systems.[citation needed] All mission parameters are pre-settable before launch, for full autonomous operation, with the possibility of operator intervention throughout the mission.[citation needed]
Communications to and from the vehicle are via RF while the vehicle is surfaced and via acoustic communications systems when the vehicle is underwater.[citation needed]
Payloads
As standard the vehicle is equipped with a suite of environmental sensors. Other payloads are mission or role specific and can include sonar systems, mine countermeasures and even other UUVs such as Archerfish.
A remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform tasks such as valve operations, hydraulic functions and other general tasks within the subsea oil and gas industry. ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of flexible flowlines and umbilicals, and component replacement.
A diver propulsion vehicle (DPV), also known as an underwater propulsion vehicle, sea scooter, underwater scooter, or swimmer delivery vehicle (SDV) by armed forces, is an item of diving equipment used by scuba divers to increase range underwater. Range is restricted by the amount of breathing gas that can be carried, the rate at which that breathing gas is consumed, and the battery power of the DPV. Time limits imposed on the diver by decompression requirements may also limit safe range in practice. DPVs have recreational, scientific and military applications.
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs.
The AN/BLQ-11 autonomous unmanned undersea vehicle is a torpedo tube-launched and tube-recovered underwater search and survey unmanned undersea vehicle (UUV) capable of performing autonomous minefield reconnaissance as much as 200 kilometers (120 mi) in advance of a host Los Angeles-, Seawolf-, or Virginia-class submarine.
Unmanned underwater vehicles (UUV), sometimes known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input.
A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter in one hull. The term MCMV is also applied collectively to minehunters and minesweepers.
The BAE Systems HERTI is an unmanned aerial vehicle (UAV) developed by the British company BAE Systems. HERTI stands for "High Endurance Rapid Technology Insertion" and was developed in Warton, United Kingdom. The HERTI airframe is based on the J-6 Fregata motor glider designed by Jaroslaw Janowski of J&AS Aero Design in Poland. Its first flight was in December 2004 at the Australian Woomera test range where much of the test flight programme has been undertaken. HERTI was also the first UAV to fly in the UK with the flight being certified by the Civil Aviation Authority.
Explorer autonomous underwater vehicle (AUV) is a Chinese AUV developed in the People's Republic of China (PRC),first entering service in November 1994. It should not be confused with another two Anglo-American AUVs that share the same name: the American Autonomous Benthic Explorer AUV (ABE) built by Woods Hole Oceanographic Institution, and the British Columbia-based International Submarine Engineeringbuilt Canadian Explorer AUV, which is based on its earlier ARCS AUV.Many Chinese AUVs later developed, such as Wukong, WZODA, CR series, Exploration series, Micro Dragon series, Sea Whale series, Submerged Dragon series AUVs, are all based on experienced gained from Explorer AUV.
The ASW Continuous Trail Unmanned Vessel (ACTUV) is a DARPA funded project launched in early 2010 to develop an anti-submarine drone. ASW is an acronym for Anti-Submarine Warfare.
