The expected delivery date of the lead ship US Coast Guard (USCG) Polar Security Cutter (PSC) appears to be unknown, according to the US Government Accountability Office (GAO).

“Contract delivery date for the lead ship is May 2025, which is one year later than initially planned,” the GAO noted in a 20 April report on acquisitions made by the US Department of Homeland Security (DHS), which is the parent department for the USCG.

“However, officials stated that May 2025 is no longer realistic because of challenges such as Covid-19 effects and the shipbuilder's inexperience with large government acquisitions,” the GAO reported. “The programme does not have enough information to determine and assess a new delivery date.”

The PSC programme is intended to assist the USCG in maintaining access to Arctic and Antarctic polar regions. The service requires its PSCs to conduct multiple missions, including ice operations, defence readiness, marine environmental protection, and search and rescue.

Aselsan has outlined plans to start expanding its family of Deringöz autonomous underwater vehicles (AUVs) this year as the first prototype under development progresses through its trials programme.

Speaking to Janes at the Undersea Defence Technology (UDT) 2024 conference and exhibition in London on 9 April, an Aselsan spokesperson told that the first prototype is making good progress following the successful completion of its first diving test in early March, and the company was optimistic that the system would complete development in the first or second quarter of 2025.

The AUV will conduct further navigation and guidance testing during April before progressing to trials in deeper water in May, the spokesperson said.

Meanwhile, the company is planning to start building a second, smaller version this year, which it aims to complete by 2026, according to the spokesperson. Aselsan is planning a family of three Deringöz AUVs in total, although no timeframe has yet been set for the development of the largest version.

Turkish manufacturer Aselsan is progressing development of a miniature version of its Düfas low-frequency towed active sonar system for unmanned surface vessels (USVs), which it expects to complete this year.

Speaking to Janes at the Undersea Defence Technology (UDT) 2024 conference and exhibition in London on 10 April, an Aselsan spokesperson said the company has been working on the smaller version, dubbed Düfas-M, since 2022.

The company is now progressing through tests of the individual hardware components, which it expects to complete in the coming months. Sea trials of the complete system integrated onboard a Marlin USV will start in the second half of 2024, with a view to completing development by year-end, he said.

Developed under the leadership of Türkiye's Defence Industry Agency (SSB) to meet the requirements of the Turkish Navy, Düfas is designed for long-range anti-submarine warfare and surveillance.

Aselsan officially unveiled the full-scale version of Düfas for use on surface combatants in March 2024 following the successful completion of sea trials in late 2023.

Navy League 2024: Findings from shipbuilding review spur US Navy secretary to seek foreign aid

Rocked by results of a recently completed shipbuilding study lambasting progress on new aircraft carriers, submarines and other major US Navy (USN) programmes, USN Secretary Carlos Del Toro is looking elsewhere for advice and examples to improve USN shipbuilding efforts.

“As the findings of the 45-day comprehensive shipbuilding review have underscored, too many of our industry partners are behind schedule and over budget on our highest priority programmes,” Del Toro said on 9 April during a keynote speech at the Navy League Sea-Air-Space 2024 global maritime exposition in National Harbor, Maryland.

“We build the most capable warships in the world in shipyards that are decades behind the global technological standard,” Del Toro said. “This is an inefficient approach requiring far too much time, workforce, and taxpayers' dollars. It is certainly an approach that is wholly inadequate to pace our 21st century competitors.”
