WASHINGTON - The Government Accountability Office on Thursday faulted the US Navy's plan to spend US$3.7 billion (S$4.65 billion) to develop, build and field a new unmanned carrier-based warplane without subjecting the programme to a rigorous review until 2020.
In a report for lawmakers, the congressional research agency criticised the Navy's plan to skip a "Milestone B" review until after initial deployment of the plane in 2020, arguing that this strategy would limit Congress' ability to oversee the programme and hold it accountable for schedule, cost and performance.
Major acquisition programs are required by the Pentagon to undergo a comprehensive review after its preliminary design has been approved. At that "Milestone B" review, senior defence officials look at the military requirements and independent cost estimates for the programme, and certify that it has reasonable cost and schedule estimates.
In this case, the Navy has argued that it can put off the Milestone B review until after 2020 because the Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) plane is a technology-development project.
Lockheed Martin Corp, Northrop Grumman Corp, Boeing Co and privately-held General Atomics have all expressed interest in bidding for the UCLASS programme. The Navy has awarded the four companies preliminary contracts for early designs and plans to issue a formal request for proposals in 2014.
The Navy plans to deploy from 6 to 24 unmanned planes for use on up to four aircraft carriers during the initial phase of the UCLASS programme. It would use the planes mainly for surveillance and reconnaissance missions, especially at night, complementing the manned fighters on board the carriers.
The GAO report said the Navy's approach would exempt the programme from cost-growth thresholds and periodic reports on its cost, schedule and performance, giving lawmakers less oversight.
The report recommended requiring the Navy to hold a Milestone B review, and suggested lawmakers should limit funding for the programme if the Navy refuses to comply.
