US Navy Railgun starts fire on the field (video)

Radical new weapon set for its first tests outside the lab

“Railguns and other directed-energy weapons are the future of maritime superiority,” said Dr. Thomas Beutner, head of ONR’s naval air warfare and weapons department. “The U.S. Navy must be the first to field this leap-ahead technology and maintain the advantage over our adversaries.”

An electric pulse is sent to the railgun which creates an electromagnetic force which releases the projectile at Mach 6, or 4,500 mph.

The immense kinetic energy generated by the hypersonic weapon is then transferred to the target on impact, obliterating it.

The electromagnetic force generated can be adjusted, depending on range of the target.

Russia launches 6th ship of The Project 20380 (Steregushchy-class corvette)

The launching ceremony has been held on 28th July at the Amur shipbuilding yards in the Far East of Russia.

Gromkiy is the sixth corvette in the Steregushchy-class and is expected to be delivered to the navy in 2018.

The Navy plans to have least 20 project 20380 corvettes for all four major fleets. Four ships of this class have already joined the Baltic Fleet.

The main missions include protection of territorial waters, exclusive economic zone, continental shelf, offshore areas, naval bases and ports. The Steregushchy class can be deployed in coastal patrol, escort and anti-submarine warfare (ASW) operations, as well as to support amphibious assaults. The corvette can engage surface ships, submarines, aircraft and shore-based targets.

The corvette has the following characteristics:

– Displacement: standard: 1,800 tons, full: 2,200 tons

– Length: 104.5 m (343 ft), beam: 11.6 m (38 ft), draught: 3.7 m (12 ft)

– Speed: 27 kn (50 km/h; 31 mph)

– Range: 3,800 nmi (7,000 km; 4,400 mi) at 14 kn (26 km/h; 16 mph)

– Endurance: 15 days

The ship features an aft hangar and flight deck for a single Ka-27 ASW helicopter.



USS John P. Murtha (LPD-26) Completed Final Post-Delivery Trials on July 21

Amphibious transport dock USS John P. Murtha (LPD-26) is ready for deployment.

USS P. Murtha (LPD-26) is the 10th San Antonio-class amphib to join the fleet. These LPDs transport and deploy combat and support elements of Marine Expeditionary Units. San Antonio-class ships carry surface connects such as amphibious assault vehicles and landing craft, and vertical lift connectors such as the H-1 and CH-53E helicopters and MV-22 Osprey tiltrotor.


USS P. Murtha (LPD-26) has been commissioned into the Navy in October 2016 and has spent the last nine months working through post-delivery test and trials with the Navy’s Board of Inspection and Survey (INSURV). The amphib returned to its homeport at Naval Base San Diego on July 21 following the final post-delivery test event, Final Contract Trials.

Two additional San Antonio-class ships, Portland (LPD-27) and Fort Lauderdale (LPD-28), are currently under construction at Ingalls Shipbuilding yard in Pascagoula, Miss.

Australia receives first air warfare destroyer

HMAS Hobart (DDG-39) has been delivered to Australian Navy.

HMAS Hobart is the first Aegis-equipped ship to be delivered to Australia.

Hobart is 146.7 metres long, has a top speed of 28 knots (52km/h), a range of about 5000 nautical miles and room for more than 200 crew.

Australia Minister for Defence Industry Christopher Pyne said: “The acceptance of this first-of-class ship is a further demonstration of the success of the Government-led reform initiative, with the program meeting all budget and schedule targets, Hobart will enter into service later this year.

“Hobart will play a critical role for Defence by providing new interoperable capabilities for the Royal Australian Navy.”

The Aegis weapon system has been designed as a total combat management system from detection to engagement.


Lockheed noted that the centralised, automated, command-and-control weapons control enables multi-mission capability, network centric warfare, cooperative engagement capability and growth to SM-6 and future capabilities.

She carries a range of weapons, detection and electronic warfare systems onboard, which include an Aegis threat tracking system, SPQ Horizon Search Radar, 48 vertical launch missile cells, a 5″ gun for coastal operations and two quad launchers of anti-ship HARPOON weapon systems.

The AWDs have also been equipped with anti-surface, anti-submarine and naval gunfire capabilities.

USS Ralph Johnson (DDG-114) Successfully Completed Builder’s Trials

US Navy stated that The future USS Ralph Johnson (DDG 114) successfully completed builder’s trials, July 20, after spending four days underway in the Gulf of Mexico.

While underway, DDG 114 successfully demonstrated full-power runs, self-defense detect-to-engage exercises, steering checks, boat handling, and anchoring.

The DDG 51 class ships currently being constructed are Aegis Baseline 9 Integrated Air and Missile Defense destroyers with increased computing power and radar upgrades that improve detection and reaction capabilities against modern air warfare and ballistic missile defense threats. The Aegis Combat System will enable DDG 114 to link radars with other ships and aircraft to provide a composite picture of the battle space. When operational, DDG 114 and her sister ships will serve as integral players in global maritime security.

The future USS Ralph Johnson will return to sea to conduct acceptance trials with the Navy’s Board of Inspection and Survey. During acceptance trials, all systems and gears will be inspected and evaluated to ensure quality and operational readiness prior to the Navy accepting delivery.
