The Spearhead-class joint high speed vessel (JHSV) is a United States Navy-led shipbuilding program to provide "a platform intended to support users in the Department of the Navy and Department of the Army. The Joint High Speed Vessel (JHSV) program is a cooperative effort for a high-speed, shallow draft vessel intended for rapid intratheater transport of medium-sized cargo payloads. The JHSV will reach speeds of 35–45 knots (65–83 km/h; 40–52 mph) and will allow for the rapid transit and deployment of conventional or special forces as well as equipment and supplies."
The JHSV has a flight deck for helicopters and a load ramp that will allow vehicles to quickly drive on and off the ship. The ramp is suitable for the types of austere piers and quay walls common in developing countries. JHSV has a shallow draft (under 15 feet (4.6 m)).
A JHSV is essentially an aluminum twin-hull catamaran shell containing four diesel engines, rudimentary control facilities for up to 40 crewmembers, and 312 airline-style passenger seats, along with an expansive flight deck on the top. The rest of the vessel is an empty 20,000 sq ft (1,900 m2) mission bay that can be loaded to carry whatever cargo is needed. Vehicles and cargo are loaded and unloaded by a ramp that can support up to 100 tons of weight. Although designed for a military crew of 46, the ships usually have a crew of just 26 mariners. The passenger room contains reclining seats with overhead televisions and racks for weapons and equipment. A vessel has 104 permanent berthing spaces. Without resupply, it can support 312 embarked personnel for four days, or 104 personnel for 14 days.
The U.S. 4th Fleet has expressed interest in using the JHSV as a low-cost ship for performing drug interdiction missions around Central and South America. U.S. Southern Command is experiencing a shortage of Navy frigates and Coast Guard cutters available to interdict drug runners due to ship age and budget cuts. In May 2013, the HSV-2 Swift conducted a drug interdiction patrol, showing an aluminum catamaran was capable of performing the role. A JHSV costs less than a frigate, has a smaller crew demand of 22 compared to 200 for a frigate, and is capable of embarking a Coast Guard Law Enforcement Detachment (LEDET).
The JHSV has no weapons or defensive systems to fulfill combat missions, but the Navy is looking to expand its roles to include re-supplying special operations forces and conducting humanitarian assistance missions. Chief of Naval Operations Jonathan Greenert has suggested using the ships as a cheaper way to perform counter-piracy missions to free up blue-water combatants. Offensive armament and defensive measures against pirates would be handled by a security team onboard, and a JHSV's speed would also be a good defense against an attack by pirates.
The control system for this class is provided by General Dynamics Advanced Information Systems through an open architecture computing infrastructure (OPEN CI). OPEN CI includes the information technology (IT) infrastructure for the combat and seaframe control systems. The infrastructure integrates the ship's electronic systems including, internal and external communication, electronic navigation, aviation and armament systems. The General Dynamics OPEN CI is also used on the Independence-class littoral combat ship (LCS), also built by Austal.
The Communications suite for this class will be provided by BAE Systems Inc.
On 7 April 2014, the U.S. Navy announced that a prototype electromagnetic railgun will be installed onto USNS Millinocket (JHSV-3) for at-sea testing in FY 2016. Though the ships are non-combatants, they were chosen for their available cargo and topside space and schedule flexibility. They will not be permanently installed on the JHSV, and the Navy has yet to decide which ship classes will receive a fully operational railgun. The tests are to offer lessons to incorporate into a future tactical design and to gain knowledge on how to integrate the system onto a ship with modifications.
The USMC is investigating changes to the JHSV ramp to allow it to place Amphibious Combat Vehicles into the water near the shore. A single JHSV could carry and deploy as many as 20-30 ACVs.
Marine Corps General John M. Paxton, Jr. has called the JHSV "a very capable ship" for certain missions, but in consideration for serving as an alternate platform for Marines to use in amphibious operations as substitutes for amphibious assault ships, he claims several deficiencies including ability to operate in difficult sea states, ability to remain survivable in contested waters, a flight deck that cannot handle the heat of an MV-22 Osprey's engines during take-off and landing, lack of a well deck to launch amphibious vehicles at sea, as well as current lack of a "splash capability" where the ramp can allow vehicles to be driven off it into the sea.
The JHSV program received Milestone A approval in May 2006. The Navy awarded Phase One preliminary design contracts in early 2008, and a detail design and construction contract in the 4th Quarter of FY08.
The Navy's Program Executive Office, Ships will conduct acquisition for both the Army and Navy, but each service will fund its own ships. After delivery, each service will be responsible for manning, maintaining, and providing full lifecycle support for its vessels.
The Navy expected to purchase 23 JHSV vessels over 30 years.
On 2 May 2011, all Army JHSVs were transferred to the Navy.
On 5 December 2012, the first ship in the class, USNS Spearhead, was delivered to Military Sealift Command in Mobile, Alabama.
On 30 June 2011, Austal was awarded construction contracts for JHSV-6 and JHSV-7.
On 27 February 2012, Austal was awarded construction contracts for JHSV-8 and JHSV-9.
On 10 December 2012, the Navy awarded its final option under its current contract, and ordered JHSV-10.
On 5 April 2013, the JHSV program was added to the remit of the Littoral Combat Ship Council, so that the capabilities of both ship types could be considered together.
In 2014, the USN considered outsourcing the management of the fleet, but concluded that the ships would continue to be manned by civil service mariners.

The Army and Navy have been operating HSVs for some years, notably HSV-X1 Joint Venture (joint Army/Navy), HSV-2 Swift (Navy), USAV Spearhead (TSV-X1) (Army), and MV Westpac Express (HSV-4676) (Navy).
In 2013 a Frost & Sullivan report predicted that sales could be made to APAC countries.
In early 2014, Austal announced it had been awarded a $124.9 million contract for two High Speed Support Vessels (HSSV) for a foreign customer, later revealed to be the Royal Navy of Oman. The HSSV has a similar catamaran hull design as the JHSV and supports naval operations including helicopter operations, rapid deployment of military personnel and cargo, and search and rescue missions. It is 72.5 m (238 ft) long and can travel at 35 knots. An HSSV has a crew of 69 personnel, can seat another 250, and has a cargo capacity of 320 tonnes (350 short tons). Both are to be delivered by 2016.
