STOBAR ("short take-off but arrested recovery" or "short take-off, barrier-arrested recovery") is a system used for the launch and recovery of aircraft from the deck of anaircraft carrier, combining elements of "short take-off and vertical landing" (STOVL) with "catapult-assisted take-off but arrested recovery" (CATOBAR).
Aircraft launch under their own power using aski-jump to assist take-off (rather than using acatapult). However, the planes are conventional, rather than STOVL aircraft, and thus requirearrestor wires to land on the ship. The STOBAR system is simpler to build than CATOBAR. As of 2018[update], it has been used widely on Russian, Indian, and Chinese carriers.
Compared to CATOBAR, STOBAR is less expensive to develop. It is easier to operate than a CATOBAR configuration, which requires large number of operators to launch the aircraft. The lack of any moving parts in a ski-jump makes it less expensive to maintain than a catapult.[1][2] It does not require any additional system to generate force required to launch the aircraft, unlike CATOBAR where an external force is needed to be generated either fromsteam catapult[3] orElectromagnetic Aircraft Launch System (EMALS)[4] to launch the aircraft.
One major limitation of STOBAR configuration is that it only works withfighter aircraft that have a highthrust-to-weight ratio such asSu-33 orMiG-29K and thus limits the kind of aircraft that can be operated from the carrier. It is not known[who?] what restrictions ski-jump takeoff implies on maximal aircraft weight. According to some sources, in order to become airborne, the aircraft may be required to limit its weaponry and fuel package in order to reduce the launch weight of the aircraft.[1][5] However, according to other sources,[6] theSuper Hornet can take-off from a ski-jump with a significant weapons load. Using ski-jump can limit the ability to conduct sorties faster on STOBAR aircraft carrier.[7] STOBAR carriers must maintain a speed of 20–30 kn (37–56 km/h) in order to generate wind speed required on deck which is essential for conducting aircraft launch operations.[8]
As of March 2025, three countries currently operate STOBAR-type carriers; Russia, India and China have built a STOBAR ship for operation, while both India and China have procured STOBAR ships that were built by Russia and have had them converted for their own use.

In our simulation, we discovered that not only could the Super Hornet take-off from a ski-jump, but could do so with a significant weapons load.
