   The Kaman SH-2G Super Seasprite is a modernized and upgraded version of the previous SH-2 Seasprite. The first prototype flew in 1985. It was a conversion form the previous SH-2F anti-submarine helicopter with uprated engines. The type entered service in 1991. As its predecessor the Super Seasprite has the same missions. It is a ship-based long-range anti-submarine helicopter. Secondary missions are search & rescue, anti-shipping, liaison and utility operations. It is also used for surveillance and over-the-horizon targeting. The Super Seasprite can operate from coast guard cutters, offshore patrol vessels, such as corvettes, frigates, and other larger ships with a landing deck.

   Despite its versatility and multi-mission capability the SH-2G Super Seasprite was retired from the US Navy in 2004. However other nations, such as Egypt, New Zealand, Peru and Poland are actively using this helicopter.

   The Super Seasprite has a crew of three, including pilot and tactical operators. The pilot flies the helicopter, while the tactical operator operates weapons and sophisticated systems.

   This helicopter has a modular cargo compartment, that can be reconfigured to suit different missions. It can transfer personnel and cargo. With sonobuoy system removed the SH-2G can carry up to 4 passengers, 2 stretchers, or up to 1 814 kg of cargo can be carried as a slung load.

   The Super Seasprite can be used for mine detection. For this role, the SH-2G can carry the Kaman-developed Magic Lantern device, a laser detector that finds mines from the water's surface to below the keel depth of most warships. For the search & rescue operations the Super Seasprite has a foldable 270 kg capacity rescue hoist and 1 810 kg capacity external cargo hook.

   The SH-2G was the last remaining helicopters used by the US Navy to fly the LAMPS I anti-submarine warfare missions. This helicopter has a low frequency dipping sonar, onboard radar, front-mounted FLIR system, aquatic data processor. The system can receive data from more than 100 sonars.

   Currently active-duty fleet of SH-60 helicopters now carries the improved LAMPS III system. At some point the US Navy has re-roled the two Naval Reserve SH-2G squadrons to carry out new missions. If required the SH-2G can be used for medical evacuation, support amphibious assault, or perform battle damage assessment.

   This helicopter can be fitted with various armament. It can carry a variety of air-to-surface missiles, such as AGM-119 Penguin anti-ship missiles, AGM-65 Maverick and MK50 torpedoes. The helicopter has provision for two machine guns. Various machine guns can be carried, such as the M60 or M134 Gatling gun.

   The SH-2G is powered by two T700-GE-401 turbo shaft engines, developing 1 723 shp each. In case of malfunction or damage the helicopter can fly with one engine. Rotor blades have reduced vibrations, for longer life of components and reduced fatigue for crewmembers.

   The fuselage of this helicopter was specially designed for maritime operations. The rotor blades are foldable to make deployment on ships easier.

   The helicopter has chaff and flare dispensers, side suppression system, ballisticaly tolerant fuel cells. Pilot and tactical operator are seated on energy absorbing crashworthy seats. Also there are emergency floatation devices.

   Rebuilt SH-2G helicopter use modern commercial off-the-shelf naval systems and equipment, such as integrated glass cockpit, digital automatic flight control system, modern navigation and communication systems. This helicopter can operate at day/night and in all weather conditions.

   An interesting feature of this helicopter is that it can refuel in air by winching a fuel pump from the deck of the ship. This method can be used in adverse weather conditions.
