KAMAN SH-2G SUPER SEASPRITE
The Super Seasprite is a high performance, all-weather Anti-Submarine Warfare (ASW) helicopter with anti-surface warfare, Search and Rescue (SAR) and utility capabilities.
A unique design feature of many Kaman helicopters is the use of a trailing-edge servo flap, used for blade pitch control. The Seasprite prototype was the single engine HU2K-1, and its first flight was on 2 July 1959.
Following flight testing at Patuxent River, Fleet deliveries began on 18 December 1962 to Helicopter Utility Squadron One at Naval Auxiliary Air Station Ream Field, California. These two squadrons provided
detachments aboard all Fleet aircraft carriers serving as utility and as SAR plane guards. In 1962, the designation was changed to UH-2A under the tri-service designation system. The UH-2B model was
a simplified model for Visual Flight Rules operations only. The UH-2C introduced the twin General Electric T-58 engines. The HH-2C followed, adding a 7.62-mm minigun in a nose turret and two in-waist
positions This model also included dual main landing gear wheels, a four-bladed tail rotor, an upgraded transmission, new engines and an increased gross weight capability. These features, with the
exception of the armament, were carried over to the HH-2D.The SH-2D, produced as the Light Airborne Multi-Purpose System (LAMPS), introduced a search radar in the radome under the forward fuselage
including provisions for two MK 46 torpedoes. The SH-2F featured a relocation of the tail landing gear to improve shipboard compatibility and improved main rotor. The SH-2G Super Seasprite was upgraded
with new avionics and with two General Electric T-7C0-GE-401 engines, replacing the T-58 engines. The Seasprite underwent continual test and evaluation at Patuxent River.
Our display helicopter, SH-2G BuNo 161642, was accepted in the Navy's inventory as an SG-2F in November 1983. After a tour with the Rotary Wing Aircraft Test Directorate, it joined Helicopter Anti-Submarine
Light Squadron Thirty-Two (HSL-32) in October 1984. The aircraft remained at HSL-32 until October 1991, before returning to Kaman for conversion to an SH-2G. Its first flight after the conversion was in September
1993. BuNo 161642 returned to Patuxent River in October 1993. It was involved in Dynamic Interface testing which evaluated the shipboard compatibility of helicopters including shipboard wind over deck flight
envelope expansion. This Seasprire also participated in systems testing and modification evaluation for the Fleet until its final flight in September 1997. This aircraft joined the Patuxent River Naval Air
Museum aircraft stable in July 1998.
