Lockheed received $696.6m to design and construct two Freedom-Class semi-planing monohull vessels, while Austal received $681.7m to build two Independence-Class trimaran ships.

Austal will be supported by General Dynamics Advanced Information Systems in the design, integration and testing of the ship's electronic systems for combat, networks and seaframe control, with work under the contract due to be completed by June 2018.

Lockheed is expected to deliver the vessels it is responsible for one month later.

Babcock installs Forward Island section on HMS Queen Elizabeth

Babcock integrated the Forward Island for the UK Royal Navy's new Queen Elizabeth-Class aircraft carrier at its Rosyth shipyard in Scotland, marking a key milestone in the vessel's assembly programme.

Constructed by BAE Systems, the Forward Island is a crucial component of the carrier, comprising of the main bridge and around 100 vital mission system compartments.

HMS Queen Elizabeth also features an Aft Island, which will provide independent control of navigation and air traffic control operators for the Royal Navy and be lifted into position by the end of July 2013.

Iran launches second Jamaran destroyer

Iran

The Iranian Navy launched its domestically built Mowj-Class guided missile destroyer, also known as the Jamaran 2, in an official ceremony in the Caspian Sea.

Fars News Agency alleged the new destroyer will feature advanced navigation systems and domestically-manufactured defence equipment, with the original Jamaran vessel having been launched in February 2010.

Designed with a helipad for carrying helicopters, and fitted with modern radars and electronic warfare capabilities, Jamaran is a multipurpose destroyer that combines anti-submarine capabilities with defence systems to engage in surface, air and undersea warfare.

Armed with a variety of anti-ship, surface-to-surface and surface-to-air missiles, as well as torpedoes, a smart 'Nour' (light) missile and modern naval cannons, the 94m-long Jamaran has a displacement capacity of 14,000t.

HMS Defender commissioned into fleet

HMS Defender

The UK Royal Navy's fifth Type-45 Daring-Class anti-air warfare destroyer, HMS Defender, was formally commissioned into the fleet on 21 March at Portsmouth Naval Base, UK.

The destroyer had completed trials of its upper deck gunnery systems earlier in the month, which involved a test firing of its 4.5in Kryten main gun, 30mm cannon, miniguns and validated their capabilities.

The sixth Type-45 destroyer, HMS Duncan, set sail from BAE Systems' Scotstoun yard in Glasgow for scheduled commissioning at Portsmouth Naval Base.

Launched in 2010, HMS Duncan was initially scheduled to depart last week, but was delayed due to technical problems.

US Navy conducts at-sea testing of torpedo warning system

US Navy

The US Navy started testing the Rapid Prototype Torpedo Warning System (TWS) and Countermeasure Anti-Torpedo (CAT) system onboard its final Nimitz-Class supercarrier USS George HW Bush.

The system was installed as part of the ship's planned incremental availability period, and tested by the Naval Sea Systems Command PMS 415's Surface Ship Torpedo Defense team.

During the trials, the system floated in the water to gather acoustic data, which will be used to enhance the software and enable the alert system to be more reliable when deployed in future.

The TWS/CAT is scheduled to undergo testing over the next few months aboard CVN 77, providing an opportunity for sailors to familiarise themselves with the system.
