Shavit 2 (Hebrew: "comet" – שביט) is a small lift launch vehicle produced by Israel from 1982 onwards, to launch satellites into low Earth orbit. It was first launched on 19 September 1988 (carrying an Ofek-1 satellite payload), making Israel the eighth nation to have an orbital launch capability [3] after the USSR, United States, France, Japan, People's Republic of China, United Kingdom, and India.

The Shavit 2 project is believed to have been an offshoot development, resulting from Israel's Jericho nuclear armed intercontinental ballistic missile (ICBM) program. [4] [5]

Shavit rockets are launched from Palmachim Airbase by the Israel Space Agency into highly retrograde orbits over the Mediterranean Sea to prevent debris coming down in populated areas and also to avoid flying over nations hostile to Israel to the east; this results in a lower payload-to-orbit than east-directed launches would allow. [3] [6] The launcher consists of three stages powered by solid-fuel rocket motors, with an optional liquid-fuel fourth stage, and is manufactured by Israel Aircraft Industries (IAI).

The Republic of South Africa produced and tested a licensed version in cooperation with Israel called the RSA-3 in an ultimately unsuccessful bid to produce a domestic satellite launch vehicle and ballistic missile; the South African program was closed in 1994. [7]

An earlier unrelated project called Shavit 2 was the first Israeli sounding rocket, launched on 5 July 1961 for meteorological research. [8] Shavit Three, with an altitude reported as 100 miles (160 km), was launched on 11 August 1961.


The development of Shavit 2 began in 1982. [9] Shavit was a three-stage, solid-propellant launcher designed to carry payloads up to 250 kg into low Earth orbit. It was speculated for some time and later confirmed that the first two stages of the Shavit were that of the Jericho II missile. [10]

Shavit was first launched in 1988 and because of its geographic location and hostile relations with surrounding countries, Israel had to launch it to the west, over the Mediterranean Sea, in order to avoid flying over those hostile territories to its east. The practice has continued ever since. [11]

Vehicle description

The first of the Shavit vehicles were a small, 3-stage, solid-propellant booster based on the 2-stage Jericho-II ballistic missile and developed under the general management of Israel Aircraft Industries and in particular its MBT System and Space Technology subsidiary. Israel Military Industries Systems produces the first-stage and second-stage motors, while Rafael is responsible for the third-stage motor. [12]

A planned commercial Shavit upgrade was called Next. This name is no longer used, and this proposed upgrade configuration is now called Shavit-2. Both first and second stages of the Shavit-2 use the stretched motor design of the Shavit-1 first stage.

Launch history

The Shavit has been launched 11 times, placing the payload into orbit 9 times. [13] On the 4th and 6th flights, the vehicle failed before reaching space. Most non-Israeli satellites are launched eastward to gain a boost from the Earth's rotational speed. However, the Shavit is launched westward (retrograde orbit) over the Mediterranean Sea to avoid flying and dropping spent rocket stages over populated areas in Israel and neighboring Arab countries. The Shavit is also said to be made available for commercial launches in the near future.

The September 2004 failure of the Shavit resulted in the destruction of the US$100 million Ofeq 6 spy satellite. Israel used Indian Polar Satellite Launch Vehicle in the subsequent launch for the TecSAR SAR satellite, [17] while upgrading the Shavit launcher.[ citation needed ] On the upgraded Shavit 2, the follow-up Ofeq 7 was successfully launched on a Shavit rocket in 2007.

South African RSA series

The Jericho II missile-Shavit SLV was also license produced in the Republic of South Africa as the RSA series of space launch vehicles and ballistic missiles. The RSA-3 was produced by the Houwteq (a discontinued division of Denel) company at Grabouw, 30 km east of Cape Town. Test launches were made from Overberg Test Range near Bredasdorp, 200 km east of Cape Town. Rooi Els was where the engine-test facilities were located. Development continued even after South African renunciation [18] of its nuclear weapons for use as a commercial satellite launcher. Development actually reached its height in 1992, a year after nuclear renunciation, with 50–70 companies involved, employing 1300–1500 people from the public and private sector. [19] [20] A much heavier ICBM or space launch vehicle, the RSA-4, with a first stage in the Peacekeeper ICBM class but with Jericho-2/RSA-3 upper-stage components was in development. [7] [21] [22]

In June 1994 the RSA-3 / RSA-4 South African satellite launcher program was cancelled. [23]

Proposed LK civilian launch variants

In 1998, Israel Space Agency partnered with U.S. Coleman Research Corporation (now a division of L-3 Communications) to develop the LK family of small launch vehicles. [24] In 2001, a new French joint-venture, LeoLink, between Astrium and Israel Aircraft Industries, was created to market the LK variant. [25] It is believed that in 2002 development of the LK variant was discontinued. [26]

The LK-1 was closely based on the Shavit-2, but with motors and other components built in the United States to satisfy U.S. government requirements. [24] The LK-2 was a larger vehicle using a Thiokol Castor 120 motor as its first stage. The third stage was either a standard AUS-51 motor built under license by Atlantic Research Corp., or a Thiokol Star 48 motor. All launch vehicles would have had a small monopropellant hydrazine fourth stage. [27]

A Shavit LK air-launched satellite launcher was proposed by ISA and Israel Aircraft Industries (IAI). The booster would have been a standard Shavit-1 or Shavit-2 without a first stage that would be dropped from a Hercules C-130. An alternative proposal consisted of a full launch stack carried atop Boeing 747 aircraft, similar to how the Space Shuttle was carried, through the Straits of Tiran and past the Arabian Peninsula into open sea; this called for a zoom-climb launch over the Indian Ocean, permitting the eastward boost from the rotation of the Earth rather than launching into a westward retrograde orbit over the Mediterranean, nearly doubling the maximum payload weight. [27] [28]

Intercontinental ballistic missile Ballistic missile with a range of more than 5,500 kilometres

An intercontinental ballistic missile (ICBM) is a missile with a minimum range of 5,500 kilometres (3,400 mi) primarily designed for nuclear weapons delivery. Similarly, conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries that have operational ICBMs.

Solid-propellant rocket Rocket with a motor that uses solid propellants

A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder; they were used in warfare by the Chinese, Indians, Mongols and Persians, as early as the 13th century.

Ballistic missile Missile that follows a sub-orbital ballistic flightpath

A ballistic missile follows a ballistic trajectory to deliver one or more warheads on a predetermined target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital trajectory.

Expendable launch system Launch system that uses an expendable launch vehicle

An expendable launch system is a launch vehicle that can be launched only once, after which its components are either destroyed during reentry or discarded in space. ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed. As of October 2019, most satellites and human spacecraft are currently launched on ELVs. ELVs are simpler in design than reusable launch systems and therefore may have a lower production cost. Furthermore, an ELV can use its entire fuel supply to accelerate its payload, offering greater payloads. ELVs are proven technology in widespread use for many decades.

Jericho is a general designation given to a loosely related family of deployed ballistic missiles developed by Israel from the 1960s forward. The name is taken from the first development contract for the Jericho I signed between Israel and Dassault in 1963, with the codename as a reference to the Biblical city of Jericho. As with most Israeli unconventional weapons systems, exact details are classified, though there are observed test data, public statements by government officials, and details in open literature especially about the Shavit satellite launch vehicle.

Pegasus is an air-launched launch vehicle developed by Orbital Sciences Corporation (OSC) and now built and launched by Northrop Grumman. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remains active as of 2021. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft), and its first stage has a wing and a tail to provide lift and attitude control while in the atmosphere. Notably, the first stage does not have a Thrust Vector Control (TVC) system. Pegasus is the world's first privately developed orbital launch vehicle.


The M-V rocket, also called M-5 or Mu-5, was a Japanese solid-fuel rocket designed to launch scientific satellites. It was a member of the Mu family of rockets. The Institute of Space and Astronautical Science (ISAS) began developing the M-V in 1990 at a cost of 15 billion yen. It has three stages and is 30.7 m (101 ft) high, 2.5 m in diameter, and weighs about 140,000 kg (310,000 lb). It was capable of launching a satellite weighing 1,800 kg (4,000 lb) into an orbit as high as 250 km (160 mi).

Dnepr (rocket) Converted Satan ICBM used as a satellite launch vehicle

The Dnepr rocket was a space launch vehicle named after the Dnieper River. It was a converted ICBM used for launching artificial satellites into orbit, operated by launch service provider ISC Kosmotras. The first launch, on April 21, 1999, successfully placed UoSAT-12, a 350 kg demonstration mini-satellite, into a 650 km circular Low Earth orbit.

Ofeq Israeli reconnaissance satellites

Ofeq, also spelled Offek or Ofek is the designation of a series of Israeli reconnaissance satellites first launched in 1988. Most Ofeq satellites have been carried on top of Shavit 2 launch vehicles from Palmachim Airbase in Israel, on the Mediterranean coast. The low Earth orbit satellites complete one Earth orbit every 90 minutes. The satellite launches made Israel the eighth nation to gain an indigenous launch capability. Both the satellites and the launchers were designed and manufactured by Israel Aerospace Industries (IAI) with Elbit Systems' El-Op division supplying the optical payload.

The Taepodong-2 is a designation used to indicate what was initially believed to be a North Korean two or three-stage ballistic missile design that is the successor to the Taepodong-1 technology demonstrator. In 2012 the U.S. Department of Defense assessed that the Taepodong-2 had not been deployed as a missile. The Taepodong-2 is the technology base for the Unha space launch vehicle, and was likely not intended as ICBM technology.

Rokot Russian space launch vehicle

Rokot, also transliterated Rockot, was a Russian space launch vehicle that was capable of launching a payload of 1,950 kilograms into a 200 kilometre Earth orbit with 63° inclination. It was based on the UR-100N intercontinental ballistic missile (ICBM), supplied and operated by Khrunichev State Research and Production Space Center. The first launches started in the 1990s from Baikonur Cosmodrome out of a silo. Later commercial launches commenced from Plesetsk Cosmodrome using a launch ramp specially rebuilt from one for the Kosmos-3M rocket. The cost of the launcher itself was about $15 million in 1999; The contract with ESA for launching Swarm in September 2013 was worth €27.1 million.
