International interest in the US/UK Joint Strike Fighter (JSF) programme continues to grow, with Australia the latest to sign for the project as an observer.

Meanwhile, US industry officials believe that Singapore may be the next to join the JSF project as a so-called "informed participant". Others which have previously enlisted in the JSF research effort are Canada, Denmark, the Netherlands and Norway. Australia signed a memorandum of understanding earlier this month, allowing for an informed observer status on the JSF programme in exchange for a $10 million contribution towards JSF research and development.

The Royal Australian Air Force (RAAF) will need to replace its 75 Boeing F/A-18 Hornet strike aircraft by 2015, and 21 General Dynamics F-111Cs and 15 F-111Gs five years later. RAAF officials aim to determine whether the JSF is a suitable candidate.

Singapore is also discussing participation in the project with the US Department of Defense, but wants a reduction in the $10 million entry fee. Italy has also been briefed on the project.

Boeing and Lockheed Martin are building rival demonstrator JSF aircraft from which three models may eventually emerge with conventional and short take-off capabilities for the US Air Force, US Navy and the Royal Navy.
