Kaman SH-2G Super Seasprite Naval anti-submarine warfare helicopter

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.


Kamov Ka-25 Anti-submarine warfare helicopter

The Kamov Ka-25 (NATO reporting name ‘Hormone’) was a naval helicopter, developed for the Soviet Navy in the USSR from 1958. Designed to meet a 1957 Soviet navy requirement for a new shipborne Anti-Submarine Warfare (ASW) helicopter, the first member of the Ka-20/25 family was the Ka-20 Harp, which initially flew during 1960. The production Ka-25BSh Hormone-A was of near identical size and appearance, but was fitted with operational equipment and uprated GTD-3F turboshaft engines (from 1973 these were replaced by GTD-3BMs). It entered service with the Soviet navy in 1967.
It was the first Soviet helicopter, developed specially for maritime use. Its coaxial design with lack of a tail rotor gave the helicopter smaller dimensions and reduced footprint on ships.
Although the lower part of the fuselage was sealed and watertight, the Ka-25 was not intended for amphibious operations, and flotation bags were often fitted to the undercarriage for use in the event of a emergency landing on the water. The cabin was adequate for the job, but was not tall enough to allow the crew to stand upright. Progressive additions of new equipment made the interior more cluttered.
It has been estimated that some 260 of the 450 or so Ka-25s produced were Hormone-As. After collapse of the Soviet Union a number of helicopters were passed on to Ukrainian Navy. By 2010 only a handful remained in Russian and Ukrainian service, mostly fulfilling secondary roles. Small numbers of Ka-25BShs have been exported to Bulgaria, India, Syria, Vietnam and former Yugoslavia. These ASW helicopters were replaced by the newer Ka-27 and its export version, the Ka-28.

Kaman K MAX New, Unique Helicopters in Yuma’s Fleet

The Marine Corps’ first two Kaman K-MAX Helicopters arrived at Marine Corps Air Station Yuma, Ariz., Saturday, May 7, 2016. The K-MAX will be added to MCAS Yuma’s already vast collection of military air assets, and will utilize the station’s ranges to strengthen training, testing and operations across the Marine Corps. The Kaman K-MAX (Company designation K-1200) is an American helicopter with intermeshing rotors (synchropter) by Kaman Aircraft. It is optimized for external cargo load operations, and is able to lift a payload of over 6,000 pounds (2,722 kg), which is more than the helicopter’s empty weight. An optionally remote controlled unmanned aerial vehicle version is being developed and is being evaluated in extended practical service in the war in Afghanistan.
