A3SM: A True Game Changer for Submarines Self Defence against Threats from the Sky
 
As part of the Paris Air Show Navy Recognition was invited by DCNS to visit their factory located near Angoulême in southwestern France. The site specializes in the production of submarine equipment such as torpedo tubes and torpedo handling systems. It is also the place where the FREMM frigates' vertical launch systems are produced. The focus of the visit however was the A3SM, a new anti-air defence weapon system for submarine currently under development by DCNS and MBDA.

X-47B UCAS-D First Catapult Launch from USS George H.W. Bush (CVN-77) a Success
 
The X-47B Unmanned Combat Air System demonstrator (UCAS-D) completed its first ever carrier-based catapult launch from USS George H.W. Bush (CVN 77) off the coast of Virginia today. "Today we saw a small, but significant pixel in the future picture of our Navy as we begin integration of unmanned systems into arguably the most complex warfighting environment that exists today: the flight deck of a nuclear-powered aircraft carrier," said Vice Adm. David Buss, commander, Naval Air Forces, the Navy's "Air Boss".

Vladivostok, Russian Navy future Mistral class LHD, specificities and characteristics
 
STX France shipyard in Saint Nazaire is currently assembling the bow and central sections of Vladivostok, the first Mistral class LHD amphibious vessel ordered by Russia. First cut of steel for this head unit took place at the Russia’s Baltic Shipyard United Shipbuilding Corporation (OCK) in St. Petersburg in August 2012.

Models of Royal Navy future Carrier & RFA Tanker simulate Replenishment At Sea
 
Two highly-accurate one-tonne scale models of HMS Queen Elizabeth and future tanker RFA Tidespring have been tested in Europe’s largest indoor water tank in Gosport to determine how the two ships can sail safely in company. Key to any future operations by the carrier – the largest warship ever to sail under the White Ensign – will be sustaining her thousands of miles from home.

DCNS Lorient Shipyard Visit and FREMM Frigates Program Update with Vincent Martinot-Lagarde
 
Navy Recognition was recently invited by DCNS to visit their Lorient (Brittany) based shipyard. The Lorient site specializes in surface vessel. It was the birthplace of many French Navy vessels such as Aviso type ships, the La Fayette class of frigates (and its export derivatives) and even several classes of cruisers before and after World War II. We also took this rare opportunity to sit down and ask a few questions to Vincent Martinot-Lagarde, FREMM Programs Manager.

Q&A with BAE Systems on Type 26 Frigate Design Update at Euronaval 2012
 
During Euronaval 2012 in October last year, BAE Systems Maritime – Naval Ships showcased a Type 26 “Global Combat Ship” frigate model with a slightly modified design compared to the big design update unveiled during DSA 2012 in April last year. We asked a few questions to BAE Systems on the reasons behind the latest changes to the design.

Commonality and similarity in DAMEN SIGMA designs
 
SIGMA 9813 and SIGMA 10513 have 100% commonality in structure, propulsion and auxiliary systems, as the 10513 version in essence is just a lengthened version and has an extra compartment of 7.20 m by a parallel section in the amidships region. This extra compartment provides added functional spaces and some alternative accommodation spaces.
