The Hypersonic Air-breathing Weapon Concept, or HAWC, was developed as a missile for land attacks, but could reportedly be used for maritime strikes soon. The US authorities earlier awarded Lockheed Martin, who manufactures the F-35 fighters, a $928-million contract to develop it. They are expected to fly for the first time this year.

The US-based defence giant Lockheed Martin has presented the concept for its HAWC hypersonic air-breathing missiles for the US Navy's F-35C Joint Strike Fighter, The Drive reports. The company demonstrated a visual version of the stealth fighter, carrying a missile under each wing, at the Navy League's annual Sea, Air, Space convention in the US. The first flight with the HAWC, which was initially developed as a land attack weapon, is to take place before 2020.

As the outlet points out, the F-35C jet is pictured carrying the missiles externally, which could impact its stealth qualities. However, the fighters will get an intrinsic stand-off capability thanks to the speed and the range of the hypersonic missiles.

The maritime strike variant of Lockheed Martin's hypersonic missile and its follow-on variants could also be used by other Navy fighters, namely the F/A-18E/F Super Hornet, larger platforms, like the P-8A Poseidon patrol jets or B-1 or B-52 bombers, The Drive suggested. It noted, however, that these developments seemed far from being in the implementation stage.

The new generation hypersonic weapons, like HAWC or the unpowered boost-glide vehicle, developed under another US programme, Tactical Boost Glide (TBG), is believed to be a game-changer for striking time-sensitive and critical targets. Its manoeuver characteristics make it harder to defend against in comparison to ballistic weapons.

Last year, the US Air Force with the US Defense Advanced Research Projects Agency (DARPA) agreed to pay Lockheed Martin $928 million to develop hypersonic air-breathing missiles. The Drive points out that the HAWC's first flight is to take place in the next fiscal year, which begins in October and runs until September 2020.

Raytheon to provide U.S. Marines with Naval Strike Force Missile
Washington (UPI) May 8, 2019
Raytheon Co. announced on Tuesday it was chosen to integrate the Naval Strike Force Missile into the U.S. Marine Corps' existing structure. The missile, which can be launched from land or sea, is a precision-strike armament which can fly at very low altitudes, and detect and destroy targets at long distances. The Navy uses the missile on littoral combat ships as an anti-ship weapon, and its selection by the Marine Corps improves interoperability and reduces costs and logistical problems. ... read more
