Some equipment can last up to 20-30 years with upgrades - just
look at our AMX13, F5s etc So I think a lot of the new stuff
we get now or in new future will still be around in 20 to 30
years time.
Air
Force
We will have F35s & probably some F16s. Maybe even
Typhoons in future ?
Upgraded AH64s will still be around. New gen of utility helis
needed to replace Super Pumas.
Maybe A400s to replace C130s
UCAVs to replace Fokker 50s.
Further upgrades to G550s - perhaps will be unmanned in the
near future.
Navy
New gen subs will replace the 2 former Vastergotlands.
Sjoormen class will be scrapped.
Victory Class will be replaced with new gen of Stealth warships
of up to 1000 tons.
Army
Leo2s may still be around in 20 years time although upgraded
with new armor, hybrid engine, optronics, all electric turret
drives, APS etc
New gen of light tanks with unmanned turret and 120 mm gun
