    is L28A1 ever used ? or it's some sort of "rename" for L27 ?
    Don't know the answer to that one but I'm fairly sure that picture was one I took at Bovington tank museum a few years ago. May be worth asking them.

    Thanks, SG 500-It now looks as if the cap is to prevent the propellant becoming damaged by transit shocks, which might happen should the sharp fins be exposed?

    Try this - http://www.bocn.co.uk/vbforum/thread...at-means-R-L-B

    Basically it is the designation used by the Royal Ordnance Factory Birtley (factory since closed and moved to new facility down the road at Washington both near Newastle).

    The factory had a brass foundry to manufacture ingots which were then turned into blanks for the production of large calibre (76mm, 105mm & 4.5" cartridge cases. It also produced the empty shells for armoured car, tank, naval and artillery systems. These were then forwarded to the filling factories (either Glascoed and Chorley [since closed] ) for completion. The foundry was later closed and the blanks were bought in instead.

    Not sure what the name is being used for the factory these days since RO was bought by BAE SYSTEMS and underwent many changes of organisation name. Last I heard a majority stake in what was left of the BAE SYSTEMS organisation (both ammunition and vehicles) has been sold to Rheimetal.

    The other items made were APDS and FSAPDS rounds for UK 105mm and 120mm tank systems. Note - the BY stencilled on the body of the L28A1 also refers to Birtley.

    This may help clarify the situation. Extract from a old Janes article on BAE Systems 120mm Tank Ammunition.

    "XL23E2 APFSDS Projectile
    In November 2006 the UK Ministry of Defence (UK MoD) announced that it was considering a programme to develop a 4th Generation tungsten projectile under the designation L28A2. The contract would be issued to BAE Systems, Global Combat Systems Munitions and would cover fabrication and test of prototypes up to, but not including, the design chill and qualification phase. They explicitly noted that this was not envisioned as a replacement for the DU-based L27 series ammunition used in the Challenger 2. The designation was therefore changed to L23A2 as it is seen more as a replacement for the first generation APFSDS L23A1 shot. British-funded firing trials to demonstrate terminal ballistics have been carried out. British qualification had been scheduled for 2009, but was held back to 2010, after which production for Oman began. The projectile will be backwards-compatible with the older L11A5 gun found in Jordanian Challenger 1s.


    The XL23E2 shot is to replace aging Omani stocks of L23A1s, and may also be procured by the British Army for use in lower-threat environments that do not require the capabilities of the L27A1 DU projectile. This takes advantage of some work done on the L28A1 developmental projectile but features the lighter projectile weight (7.95 kg) of the L23A1 and integrates with the C3TR L18A1 propelling charge. The use of the C3TR propellant extends barrel life but reduces muzzle velocity. Due to improved penetrator design, external and terminal ballistics are still better than the L23A1, but decisions are still pending on final design and production. "

    Hope this helps.
