US Coast Guard medium icebreaker Healy (WAGB-20) recently completed operations in the Beaufort Sea in support of the Arctic Mobile Observing System (AMOS) programme being developed and tested by the Office of Naval Research (ONR), Healy'sCaptain Ken Boda told Janes.

AMOS is a collection of buoys designed for use in the Arctic, as well as unmanned underwater vehicles (UUVs), meant to operate under ice-covered regions and establish two-way Arctic communications – vehicle-to-vehicle, vehicle-to-buoy, or node, and node-to-shore.

According to US Navy officials, AMOS employs Topside Command, Control and Communications (C3) software to command-and-control the UUVs, to provide health and status monitoring tools for each of the unmanned assets, and to provide operators a way to visualise and analyse relevant environmental information, including ocean currents, water temperature, salinity, and ice cover.

Recent Topside C3 updates for AMOS help support data sets containing ice information.

“We put moorings down and launched autonomous vehicles,” Capt Boda said during a ship-to-shore interview as Healy

The Royal Netherlands Navy's (RNLN's) new expeditionary survey boat (ESB), HrMs Hydrograaf (H 8021), has officially entered service.

The mini hydrographic survey vessel was formally handed over to the RNLN by the Defence Materiel Organisation (DMO) on 21 November.

Hydrograaf was designed and built by Damen Shipyards Den Helder (DSDH) under a contract awarded by the DMO in 2019. Laid down in February 2020 and launched in January 2021, the vessel was delivered to the DMO in May 2021 following the successful completion of sea-acceptance trials.

A spokesperson told Janes the planning schedule for the delivery of the boat to the navy to start operations has been impacted by a range of factors, including delays caused by the Covid-19 pandemic, time needed for crew training, additional seaworthiness certification activities, and the supply of documentation and spare parts by Damen.

ZEUS scopes combat system retrofit for DDG 1000 destroyers

by Richard Scott

USS Zumwalt arrives in Yokosuka, Japan, in September 2022. The ZEUS programme is considering opportunities to improve supportability and interoperability of the DDG 1000 destroyers by replacing unique components and systems with analogous systems common with other USN surface combatants. (US Navy)

Plans are being developed by the US Navy (USN) that would see key parts of the combat suite equipping the three DDG 1000 Zumwalt-class destroyers swapped out for command and sensor systems common to other US surface combatants.

The concept – dubbed the Zumwalt Enterprise Upgrade Solution (ZEUS) – is considering replacing a number of mission system components, including the ships' combat system software and undersea warfare suite. A sources sought notice was released by the Naval Sea Systems Command (NAVSEA) on 17 November, just days after first-of-class USS Zumwalt completed its maiden three-month deployment to the Western Pacific.

The three DDG 1000 destroyers – USS Zumwalt , USS Michael Monsoor, and the future USS Lyndon B Johnson

The design of the French Navy's next-generation nuclear-powered aircraft carrier (CVN) is continuing to evolve, with the latest iteration revealing a series of refinements to the ship's flight deck layout and island superstructure.

The Porte-Avions Nouvelle Génération (PA-Ng) programme, intended to replace the French Navy's current CVN Charles de Gaulle from 2038, was given the official go-ahead by President Emmanuel Macron in December 2020. The Direction générale de l'armement (DGA) and industrial prime contractor MO Porte-Avions (a joint venture of Naval Group and Chantiers de l'Atlantique) are undertaking systems/architecture design activity intended to mature the design baseline ahead of a transition into the definition phase in the first half of 2023.
