Primary missions of the SH-2G are anti-submarine warfare (ASW)and anti-ship surveillance and targeting (ASST). Secondary missions include search and rescue, vertical replenishment, medical evacuation, communications relay, personnel transfer,surveillance and reconnaissance, post-attack damage assessment, and naval gunfire spotting. Armament systems consist of two search stores systems (sonobuoy's and marine location marker's), an external weapons/stores system for external fuel tanks or torpedoes, and a countermeasures dispensing system.
The original SH-2 Seasprite took off on July 2, 1959, and the US Navy over the years ordered various variants. Work on the SH-2G began in the 1980s, and an engine testbed for the T700 engines, which replace the T58, flew in April 1985. A prototype with full avionics fit followed on 28. December 1989. First new production SG-2G was accepted into service with the US Navy Reserve Squadron HSL-84 at NAS North Island (San Diego) on February 25, 1993. The Super Seasprites are used for long-range surveillance, anti-surface warfare, anti-submarine warfare, mine warfare countermeasures, SAR and utility missions.
The first foreign sale of th SH-2G was announced in March 1995, when Egypt ordered 10 helicopters (all remanufactured from SH-2Fs). Official roll-out of the first SH-2G(E) was on October 21, 1997, although testing had been completed earlier. The first three machines will be used for flight training at Pensacola NAS before in-country delivery in April 1998. The helicopters will fly from frigates. Value of the deal is put at more than 150 million US-Dollars with support. Other international customers for the SH-2G are Australia (11) and New Zealand (4), which selected the Kaman helicopter after fierce competitions in January an March 1997 respectively. Contracts were signed in June, worth 600 million US-Dollars for Australia and 185 million US-Dollars for New Zealand (including training, spares and Maverick missiles). Deliveries to Australia are to start in the year 2001, and New Zealand will get its Super Seasprites from June 2000 for operation aboard ANZAC and Leander Class frigates. As an interim measure, SH-2Fs were delivered to the New Zealand Navy in 1997/98. |
