Oki - history behind that tank proposal
Soon after the initial production of the Elefante Mk.2, the federation start to design a new tank. This is a brand new model, the old Centurion – based design clearly achieved is limit.
Like many proposals of the 90’s, they go for an unnamed turret and bigger gun with autoloader.
The initial prototype have all crew in the main hull, a variant of the 120mm IMI gun with autoloader and an 7.62mm MG coaxial. Engine is an 1100hp MTU variant. The new Trophy APS / ADS system that Israel’s Rafael is designing is incorporated, but, taking advantage of the tank still in planning, the system is fully incorporated, not an add-on.
But, soon, the possibilities of new tech / design start to be perceived and the design is heavily modified.
Never satisfied that they need to get an Israel gun, the team that developed the older 105mm L62 continued to work, introduced also a 120mm gun, but too late and incompatible with the turret in use. Continuing they research, they are finishing a 140mm L51 that they call superior to any tank gun in service. The second generation turret now have – 1 140mm L51 gun (40 rounds + 8 missiles), a 7.62mm MG coaxial and a 30mm gun with 250 rounds also coaxial, and a RWS station that can use many different weapons (5.56, 7.62, 12.7, 20mm or 40x53mm grenade launcher) in a plug-n-play system. The RWS is similar to the german FLW system of OTL, but with a weight of 520kg and an elevation of 75º+. The 30mm coaxial is a variant of the one used in the fighters, but with a much reduced fire rate (‘only’ 300 rpm, instead of 1300).
The missiles are initially based on the LAHAT, but taking full advantage of the bigger diameter of the gun (140mm v 120mm) they are faster and have anti-helicopter capabilities.
The engine is upgraded to the more recent and capable 1500hp MTU (Leo 2) with an eye in the 1650hp in development. Engine compartment is modified to fast exchange and incorporate IR reduction measures. APU also included.
Crew compartment is heavily modified to include a galley (heat system for food), bed (enough space on the floor for one crew sleep at time) and toilette (very compact like in the SU-34).
Latest armor, ERA, IED protection and sensors are also incorporated.
Final design weights 58 tons and start initial production (aka advanced prototype phase) in late 2005. Very expensive, so much that production is in doubt.
Note..: Ammo – 7.62 / 3000, 30mm / 250, 140mm / 40 + 8 missiles. RWS – depend of configuration.
In my story several Israeli systems appear sooner because the portuguese federation participates in the research / funding.
Claymore - think can made a design based on that one and this data, pretty please ? The final one if possible
A 'bit' too ambitious ? Is based on many post-Cold WAR MBT's (strong influence from Strv 2000, T-14 and Merkava 4).
