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

Italian shipbuilder Fincantieri announced on 28 March that it has signed a EUR1.18 billion (USD1.27) contract for two multirole offshore patrol ships (Pattugliatore Polivalente d'Altura: PPA) with the Indonesian Ministry of Defense (MoD).

However, Indonesia's ability to fund this commitment is presently unclear given the lack of an allocation for this programme in the country's defence budget.

The PPA is a class of 143 m warships that can be configured for a wide spectrum of missions ranging from ‘light' low-tempo maritime surveillance operations to ‘full combat' higher-end warfighting scenarios. Depending on the configuration, the vessels displace between 5,800 and 6,300 tonnes.

Italy has commissioned three of the vessels and the ships were inducted between March 2022 and September 2023. The Italian Navy is expected to receive its fourth and fifth PPAs in 2024.

CRS raises USCG Polar Security Cutter cost-estimate questions

The accuracy of the estimated procurement cost of the proposed US Coast Guard (USCG) Polar Security Cutter (PSC), given its size and internal complexity, is a potential issue of concern, according to the US Congressional Research Service (CRS).

“The PSC's estimated procurement cost per weight is roughly half that of the [US] Navy's LPD-17 Flight II and LHA amphibious ships,” the CRS said in its report, Coast Guard Polar Security Cutter (Polar Icebreaker) Program: Background and Issues for Congress , released on 25 March.

“These amphibious ships are equipped with expensive combat system equipment that is not included in the PSC design, but whether this would account for all of the difference in cost per weight between the PSC design and the two amphibious ship designs is not clear,” the CRS said. “If substantial cost growth occurs in the PSC program, it could raise a question regarding whether to grant some form of contract relief to the PSC shipbuilder.”

The Republic of China Navy (RoCN) has received its fifth and sixth Tuo Chiang-class guided-missile corvettes.

Presiding over the vessels' handover ceremony on 26 March at Yilan was Taiwanese President Tsai Ing-wen who in an official social media post on the same day described the handover event as “an important step forward for Taiwan's indigenous naval defence”.

The Tuo Chiang class is a catamaran-hulled corvette that features a wave-piercing form factor with reduced radar cross-section (RCS) exteriors. It was developed by the country's National Chung-Shan Institute of Science & Technology (NCSIST) with local shipbuilder Lung Teh.

First-of-class ROCS Tuo Chiang (618) was commissioned in December 2014. The programme's second-of-class onwards are based on an improved design with a longer overall length of 65 m and a higher displacement of 685 tonnes. The first-of-class displaces about 600 tonnes and has an overall length of about 60 m.

The vessels that were handed over on 26 March are named An Chiang (625) and Wan Chiang
