Design Challenge: Land and sea/amphibious MBT
« on: 05 April 2018, 16:21:25 »
Request for proposals for: Special Purpose Main Battle Tank for amphibious, land and sea operations.

Requirements:
-Year: 3075 [maximum technology introduction date]
-Tech Base: Inner Sphere
-Faction: Federated Suns [equipment choices etc. should fit FedSuns style]
-Fully Amphibious tracked or wheeled Combat Vehicle
-Maximum weight of no more than 75 tons, lower is preferred
-Functionally a main battle tank, ton for ton effectiveness with a real MBT is not expected due to limits of Fully Amphibious modification
-No experimental technology, Advanced-level technology is acceptable [as Fully Amphibious is]
-Not an OmniVehicle

Additional requests, not required:
-Maximum speed of at least 64 KPH [4/6 movement]
-Low unit cost [I don't care about exact C-bill cost but generally speaking lower weight and simpler/older equipment is preferred provided this does not compromise unit capabilities badly]
-Equipment should be considered for the expected operating environment, consider what hostiles may be using
-Variant proposals, specifics below:
-Export variant:
--Export variant can be with or without Fully Amphibious equipment, though given the special nature of the tank, perhaps it should retain Fully Amphibious equipment or at least use Limited Amphibious
--Export variant should be downgraded but not so much as to make it uninteresting
--Export variant could be cheaper than standard variant
--If you have specific export customers in mind, could equipment be tailored for their tastes?
-3135 Upgrade variant:
--Upgrade should be upgraded to Dark Age standards circa 3135, but Dark Age Experimental technology is off the limits
--Clan-spec upgrades are acceptable but cost is a consideration, this is a combat vehicle after all
-3135 Upgrade-Export:
--Export variant restrictions apply in addition to Upgrade preferences
-Other variants that you think might be logical or useful

Notes:
-This tank may be a variant of existing design, but in such case style and flavor of the original should be adhered carefully.
-HarJel would be nice... but not really available until the Dark Age. Make of this what you will.

Bonus:
Got a reference art for how an "aquatic/amphibious tank" might look?


If using SSW, note that Fully Amphibious thing may not save properly, or perhaps it vanishes after loading design, so double check that.
I recommend using MegaMek Lab, but it seems that using faction limit option hides chassis modifications.  Fully Amphibious mod is listed as "Combat Vehicle Chassis Modification [Fully Amphibious]" in the other equipment list.
In either case Advanced tech level needs to be used.

The FAACV-1E (Frontline Amphibious Armoured Combat Vehicle - 1 Export Model) Shares many traits with the FAACV-1I.  The main changes are the armour which uses IS standard armour rather than HFF and the weapons loadout which is downgraded to a PPC and 2 MGs (rather than a plasma rifle).

These changes reduce the cost to a hair over 1.5 million c-bills.
