BAE Systems is to slow work on the Nimrod MRA4 and move ahead more cautiously than previously planned in an attempt to overcome the programme's problems.

Originally, BAE was to build three prototypes, and while it test-flew the aircraft, another seven aircraft would be manufactured for delivery shortly after conclusion of the test programme. BAE says it will build the initial three MRA4s, ensure it has the design right and then build the remaining production aircraft. The in-service date has slipped from late 2005 to 2009.

The latest problem was unearthed last year, delaying the planned first flight, when the wing structure was found to need strengthening. The company hopes to fly an aircraft this year, but it is not clear whether this will be achieved.

Meanwhile, the MoD is "considering an increase in the aircraft's capability". New roles could include long-range strike and making the aircraft a key element of the UK's intelligence, surveillance and reconnaissance fleet.
