The Kaman SH-2G Super Seasprite is an American ship-based helicopter with anti-submarine, anti-surface threat capability, including over-the-horizon targeting. This aircraft extends and increases shipboard sensor and weapon capabilities against several types of enemy threats, including submarines of all types, surface ships, and patrol craft that may be armed with anti-ship missiles. It was originally developed for the United States Navy in 1980s as a reengined version of the older Kaman SH-2 Seasprite.
In the 1990s, the Royal Australian Navy (RAN) decided that it needed an intermediate helicopter to operate from the Anzac-class frigates and the planned offshore patrol vessel (OPV); a proposed cooperative project with Malaysia, however, due to its size, the OPV could only operate a small helicopter. In 1997, the Australian Government signed a A$667 million contract with Kaman to purchase 11 upgraded Super Seasprites. By 2005, up to 40 deficiencies in the helicopter had been identified, including the inability to operate in bad weather and low-light conditions, and its failure to meet Australian airworthiness standards. The helicopters were initially restricted to transport duties during good weather before being grounded in May 2006.[
An air force, also known in some countries as an aerospace force or air army, is in the broadest sense, the national military branch that primarily conducts aerial warfare.
