THE JAPAN AIR Self-De-fence Force (JASDF) is concerned that, unless production of the Mitsubishi FS-X support fighter begins in 1996, the aircraft will not enter service in time to replace its fleet of Mitsubishi F-1s.
Many of Japan's 75 F-1s are nearing the ends of their design fatigue lives and will soon need phasing out. The JASDF hopes to begin replacing the aircraft with the FS-X from 1999 onwards, but has not yet been given approval for production from the Japanese Government.
Japan's socialist-led coalition Government, however, is waiting to complete a wide-ranging review of future defence planning and spending levels, before giving the go-ahead. The review will shape Japan's next interim five-year defence plan for the period 1996-2000
The review was due, to be completed shortly. Political instability within Japan's increasingly fragile coalition Government, however, together with the more pressing need to devote resources to earthquake relief in Kobe, is threatening to delay publication of the review.
According to Tokyo-based defence sources, the Government is instead considering pushing back its five-year plan by 12 months and substituting an interim one-year plan for 1996.
The plan is expected to contain a decision on the FS-X production timetable and the number of aircraft to be built over the next five years. The JASDF had hoped to purchase up to 130 aircraft, but this is likely to be cut to as few as 70 aircraft, divided between three support squadrons.
Military and industry officials warn that the fiscal year 1996 budget must include funding for the start of FS-X production, if the aircraft is to meet its 1999 in-service target. The only alternative would be, to reduce F-1 flying time.
