Sikorsky Aircraft has recently delivered the 400th MH-60 SEAHAWK helicopter to the U.S. Navy.
The milestone consists of 166 MH-60R anti-submarine and anti-surface warfare helicopters, and 234 MH-60S utility/armed helicopters.
"MH-60 multi-mission aircraft are among the most reliable and sophisticated maritime helicopters in the world," said Capt.James Glass, U.S. Navy Program Manager, H-60 Programs. "The Navy intends to continue flying these helicopters well into the 2030s."
MH-60S ("Sierra") helicopters carry supplies and sailors between ships, and protect U.S. ships from surface threats in an armed configuration. Sierra aircraft are expected to take on an airborne mine countermeasures role starting in 2014.
MH-60R ("Romeo") helicopters employ radar, acoustic sonar, communications links, torpedoes and air-to-surface missiles for the anti-surface and anti-submarine warfare roles.
Sierra aircraft, which entered U.S. Navy service in 2002, will remain in full rate production through 2015 as part of a currently planned production run of 275 aircraft. Romeo helicopters, operational since 2006, are currently scheduled to remain in production through 2017 to meet the Navy's 291 intended aircraft buy. The two aircraft models have accumulated a combined 660,000 flight hours to date.
All but two of the 400 MH-60 SEAHAWK aircraft delivered to date are operated by the U.S. Navy. In 2011, the Royal Thai Navy took delivery of two MH-60S helicopters via the U.S. Government's Foreign Military Sales (FMS) program.
The U.S. Navy has acquired all MH-60 SEAHAWK aircraft since 2002 via five-year contracts. The current 2012-2017 contract funds 193 MH-60R/S SEAHAWK helicopters, plus another 24 Romeo helicopters for the Royal Australian Navy. Actual production quantities will be determined year-by-year over the life of the program based on funding allocations set by Congress and Pentagon acquisition priorities.
Sikorsky will deliver the first four RAN aircraft (before mission systems integration) during 2013. Additionally, Sikorsky will deliver the first two (of nine) Romeo aircraft for the Royal Danish Navy during 2014.
