If the Army is truly committed to NGCV Class III a large caliber  (152mm or 155mm) Direct Fire/Indirect fire 40ton vehicle then there will need to be a new 20ton base vehicle (The most important vehicle and replacement for the M1 in the Army's future is a NGCV Class III IMHO.) It would only make sense that a baseline vehicle be used for the Optionally Manned Fighting Vehicle (OPMFV).

 If the Army can not pay for a new design which can house a 9 person exoskeleton equipped squad plus yet to evolve squad small UGVs (certainly not yet close to evolved and need to be DoD development based not the COTS toys) then they should just look at an extended hull, enhanced turret Bradley mounting armed VTOL UAVs (also needing a DoD development as current COTS is crap) until they are ready for new vehicle. A new propulsion strategy will cost more as well and is also is not on any "on market" vehicle.

A half measure "on the market" OPMFV would be cheaper than a new baseline vehicle and it would also obsolete before it enters service.  Overall that is a more expensive strategy than just waiting to afford a decent vehicle. No 'on the market vehicle" is "Next Generation". That is a joke.

Some Corrections from The Aviation Historian 25,

SE-1020  was a maritime-patrol version equipped with gun-turrets
SE-1030 & SE-1035  were a stratosphere transport variants,with wider fuselage
SE-1040  was a version powered by four Rolls-Royce Dart turboprop engine

that's right my dear Jemiba.

I wonder how small the engines would need to be ...

Reminds me of this design, with two really small engines :#

Give me a few days and I will copy the original article from The Aeroplane

It definitely needs wheel pants to reduce the number of rocks thrown into propellers.

Kenneth Bulmer (as Bruno Krauss), Steel Shark, 1978

Australia

HMAS Ulmurra (Ex-HMS ?)
Hunt Class Minesweeper (WWI)
Details as per the real ships.
Armament has been modified
Equipped with Hydrophones and an unspecified number of depth charges. Main armament 2 x 12 pdr guns.
Note: This ship is based (Loosely) on a real RAN ship. The HMAS Doomba (ex-HMS Wexford) was a Hunt Class Minesweeper that was converted into a passenger ferry during the interwar period and was reconverted back into an escort vessel during WWII. The dimensions the author provides for this ship match the WWI Hunt class perfectly. The Doomba's armament was actually heavier than her fictional counterpart, with the RAN fitting her with a 4 inch gun and 40 depth charges.

United Kingdom

HMS Rodney
Nelson Class Battleship
Real ship, details as in service.

HMS Ark Royal
Ark Royal Class Aircraft Carrier
Real ship, details as in service.

HMS Saltburn Head
Armed Merchant Cruiser
Built: 1924
Crew: 250
Armament: 8 x 6 inch guns (4 a side), 2 x 3 Inch AA Guns, Machine guns (Unspecified number. The only specific type mentioned are Lewis guns.)
Displacement: 16320 tons
Length: 542ft 3in (165.3m)
Engines: '...two-shaft reciprocating engines...' (15000 IHP), Single funnel
Speed: 16 knots
Note: Described as an ex-Passenger liner.

Various 'Unnamed' warships.

Germany

U-40
Type IX U-boat
Details as per the real ships
Note: Pennant clashes with a Type IXA U-boat sunk in October of 1939. In the series this novel the U-boat is still in existence in December 1939.

U-42
Type IX U-boat
Details as per the real ships
Note: Pennant clashes with a type IXA U-boat sunk in October of 1939. In the series this novel the U-boat is still in existence in December 1939.
Author anachronistically gives this ship an Fa-330 'Bachstelze' (Wagtail) towed autogyro, these did not enter service until 1943.

Rugen
Armed Merchant Ship (Commerce Raider)
Crew: 340
Displacement: 8300 tons
Armament: Unspecified number of 5.9 inch guns in concealed mounts, probably torpedoes as well.
No other details
Note: The name given to this ship does not fit the scheme Germany used for commerce raiders. As in WWI these ships were named after animals, not islands.

Plot summary: The year is 1939 and as it draws to a close the war at sea is hotting up.

Note: This is the first in an eight book series ('Sea Wolf') of novels following the career of a particular U-boat officer through the Second World War. Written by science fiction author Kenneth Bulmer under a pseudonym, this is one of several series of action novels he wrote under various pseudonym's (Adam Hardy ('Fox' A Napoleonic Naval Series & 'Strike Force Falklands' A Falklands War series.), Ken Blake ('The Professionals', TV-Tie ins.) , etc.) for the cheaper end of the paperback market in the late 1970s and early 1980s. Likely intended to cash in on the success of Edwyn Gray's U-boat novels published in the mid to late 1970s, this series was probably intended to cover the entirety of World War Two, but the last published novel only carried the series to 1942.

Yes it has it's own industry.
Part of it industrial base,it has the resources and the people.
Yes post war it gained licence to build centrifugal engines.
Scale.
The island continent is somewhere between twice the size of Madagascar to that of Western Australia. Approximately the size of the British Isles and France and Germany and Spain put together.
Temperate climate and fertile soils. Multiple large rivers flowing with fresh water. Shallow seas around.
Europeansin contact since Vasco de Gamer, stopping on the way to India and China and the spice islands.
Country D has organised society and military.
Defeated overconfident Europeans to dominate the center of the landmass.
