USNS Spearhead (T-EPF-1)

USNS Spearhead (T-EPF-1) (formerly JHSV-1) is the first Spearhead-class expeditionary fast transport operated by the Military Sealift Command. USNS Spearhead was christened on 17 September 2011.

Spearhead, as well as other ships of her class, are built to a modular design that allows them to be rapidly refitted with various equipment within a 20,000 square feet (1,900 m2) bay depending on the mission at hand. Spearhead is planned for non-combat missions, such as transportation of troops or equipment.

Spearhead is 103 metres (338 ft) long and 28.5 metres (94 ft) in beam, and has a draft of 3.83 metres (12.6 ft).

The ship is powered by four MTU 20V8000 M71L engines, each with a power of 9.1 megawatts (12,200 hp), driving four Wärtsilä WLD 1400 SR waterjets through ZF 60000NR2H reduction gears. This allows for a maximum speed of 43 knots (49 mph) and a service speed of 35 knots (40 mph).

She has space for 41 crewmembers, though under normal conditions will sail with 22, as well as sleeping accommodations for up to 150 people and an additional 312 seats for troop transport.

There are also facilities for one helicopter.
