Launch of Emile Bertin, the French Navy's third logistic support ship

The third French logistic support ship, Émile Bertin, was launched at the Chantiers de l’Atlantique shipyard in Saint-Nazaire on April 17.

The launch forms part of a Franco-Italian programme managed by the Organisation for Joint Armament Cooperation (OCCAR) to deliver six vessels.

The initiative seeks to provide four ships for the French Navy and two for Italy, with a further option for a third Italian vessel.

Following the delivery of the Italian ships Vulcano and Atalante, Émile Bertin follows the French vessels Jacques Chevallier and Jacques Stosskopf into production.

Indian Navy's newest dive support boat hits the water

Launch of the Indian Navy dive support vessel A23

Privately-owned Indian shipbuilder Titagarh Rail Systems (TRSL) recently floated out a new catamaran dive support vessel (DSV) slated for the Indian Navy.

Designated A23, the 32-metre vessel is the fourth of five DSVs that TRSL has been contracted to build for the Indian Navy. Class lead vessel A20 was handed over in 2025.

In addition to being used for dive support, the vessels may also be used for diver training in harbours and coastal waters, marine salvage, and repair/maintenance of other vessels.

Australia, Japan sign contracts to start $7b warship deal

Australia and Japan signed contracts on Saturday launching their landmark AU$10 billion ($7 billion) deal to supply Australia with warships, Tokyo's most consequential military sale since ending a military export ban in 2014.

Defence Ministers Richard Marles and Shinjiro Koizumi signed a memorandum, "reaffirming the Australian and Japanese governments' shared commitment to the successful delivery," of the warships, Marles said in a statement.

The deal struck in August anchors Japan's push away from its postwar pacifism to forge security ties beyond its alliance with the US to counter China.

Mitsubishi Heavy Industries is to supply the Royal Australian Navy with three upgraded Mogami-class multi-role frigates built in Japan from 2029. Eight more frigates will be built in Australia.
