Major US Navy (USN) shipbuilding programmes are running one to three years behind schedule due in a large part to the lack of a sufficient workforce and supply-chain disruptions, according to a 45-day shipbuilding review of these programmes and USN officials who spoke about the review's findings on 2 April during a roundtable media discussion.
While some of these issues are “lingering” Covid impacts, Nickolas Guertin, assistant secretary of the navy for research, development, and acquisition, acknowledged during the roundtable that they have become a new normal of the shipbuilding waterfront world.
“The supply chain is different now,” he said, adding some materials must be acquired much sooner than before.
In addition, he said, not only has there been a thinning of the workforce, there has also been a “greening of the workforce” – with veteran workers leaving the ranks and being replaced by younger and less-experienced workers, which also has an impact on waterfront work.

Chinese defence company Poly Technologies showcased the A2000, a new next-generation combat unmanned surface vessel (USV), at the Defence Services Asia (DSA) 2024 exhibition held in Kuala Lumpur from 6 to 9 May.
The A2000 attack USV has a length of 45 m, a displacement of 280 tonnes, and a top speed of 35 kt. It features twin diesel engines and two controllable pitch propellers.
It is equipped with an active electronically scanned array (AESA) radar for surveillance and is integrated with an eight-cell vertical launching system for launching surface-to-air missiles, and 24-cell launchers at both sides for rockets. However, it is not fitted with anti-ship missile launchers.
The USV can co-ordinate with smaller vessels for a swarm attack, provide air defence, and extend its reach via satellite connectivity. Its trimaran hull design minimises radar detection. It also supports vertical take-off and landing (VTOL) unmanned aircraft system (UAS) operations for enhanced surveillance, positioning it as a versatile asset for peacetime and conflict scenarios.

UK-based SubSea Craft has joined forces with Capewell Europe to explore the air deployability of its Victa diver delivery unit (DDU) prototype when integrated onboard the latter's newly developed Universal Maritime Craft Aerial Delivery System (UMCADS).
Speaking to Janes on 1 May, Lee Ebsworth, SubSea Craft's chief commercial officer, said the partnership has mutual opportunities as the two companies work together to increase the evidence bank for Victa as a deployable air asset as well as to demonstrate the flexibility of Capewell's UMCADS.
“While we continuously push the technological edge in our platforms to give operators the advantage, their effectiveness hinges on successful deployment into the area of operations,” he said. “We've prioritised ensuring Victa's flexibility in deployment, and conducting feasibility studies with Capewell enables us to expand the available options against the most demanding scenarios.” What is particularly valuable about UMCADS is its configurable nature, which not only supports Victa but also complements other concepts currently in development, he added.

Gibbs & Cox, a wholly owned subsidiary of Leidos, has developed a platform to meet global demand for smaller frigates, William Cowardin Jr, vice-president for global ship design, Gibbs & Cox, told Janes in April during the Navy League Sea-Air-Space 2024 global maritime exposition in National Harbor, Maryland. What the company calls the International class began as an internal research and development effort to develop a next-generation hull and test it to determine how big or small it could be and various mission packages that could be integrated, he said.
The design is simpler to construct so that it can be produced by smaller shipyards or yards that have not previously built warships. It employs mature technologies, such as the GE Aerospace LM2500 gas turbine with a basic combined diesel-electric and gas (CODLOG) propulsion architecture, Cowardin Jr said. Gibbs & Cox brings significant experience in working with shipyards, including being able to tailor production packages to meet a yard's specific needs.
