FV4201 Chieftain family

[lenny100]

A build set of members of the FV4201 Chieftain tank which may in another time have been put into service, guess if you can those which came from real thoughts and those which are mine

The FV4201 Chieftain was the main battle tank of the United Kingdom during the 1960s, 1970s and 1980s.

A development of the Centurion, the Chieftain introduced the supine (reclining) driver position to British design allowing a heavily sloped hull with reduced height. A new powerpack and improved transmission gave it higher speed than the Centurion despite being heavier due to major upgrades to armour protection and the armament: this allowed it to replace both the Conqueror and Centurion while performing their roles effectively


RAF Marksman 2 Chieftain
Following the failure of both the RAF regiment and Royal Artillery regiments to defend the airspace around the 1982 San Carlos landings during the Falklands War, several air defence systems were revisited including a self-propelled gun system.
Marksman 1 developed by Marconi, consisting of a turret, a Marconi Series 400 radar and two anti-aircraft autocannons.  The turret can be adapted to many basic tank chassis to create a self-propelled anti-aircraft gun.
The armament consists of two Swiss 35 mm Oerlikon anti-aircraft guns, with a rate of fire of 18 rounds per second. The fragmentation round has a muzzle velocity of 1,175 m/s. The effective range is 4,000 meters. The vehicle is also equipped with eight smoke dischargers, a 7.62 mm machine gun, and a flare gun. The turret can traverse a full 360 degrees and has an elevation range of −10 to +85 degrees. The magazines hold 460 fragmentation rounds and 40 anti-tank round It is considered a fully accurate anti-aircraft artillery system, having a documented hit percentage of 52.44%.
The MK2 system added round tracking aiming system radar and up-rated tracking computers. The guns were also changed to a larger calibre 40mm Oerlikon cannon with a larger magazine to hold 650 fragmentation rounds and 50 anti-tank rounds.
The RAF regiment received only 12 turrets in 1987 fitted to older Chieftain tanks which were being withdrawn from front line service with the army, whilst the Royal Artillery received 36 during the late 1980 which were also fitted to withdraw chieftain tanks.
Sixteen system were sent to defend airfields during Operation Granby in 1991.
Plans to fit the turrets to FV4030/4 Challenger 1 tanks as they were replaced with the Challenger 2 were mooted but not taken up due to July 1994 Front Line First defence cuts when all the systems were taken from service.



Chieftain Broadsword SPG tank hunter
As the first prototypes of the Kanonenjagdpanzer were built in 1960 by Hanomag and Henschel for West Germany Bundeswehr, the British army was already looking at the future.
In 1972 joint project between UK and the Bundeswehr started to look at a replacement
In Germany, tank designers had been experimenting with the Panzer VT1-1 and VT1-2 Leopard 2 chassis SPG armed with twin 120 mm cannons.
This prototype test vehicle is often called the Jagdchieftain, but its correct name is the Concept Test Rig (CTR)
The Casement Test Rig (CTR) had a semi-fixed single gun of 130 mm. The gun was set in a casement hull superstructure on a Chieftain tank chassis. A lot of aluminium was used in an effort to reduce weight.
In the early 1970s, NATO believed that to deal with an overwhelming force of Soviet armour the Allies would fall back while inflicting as many casualties as possible until more troops and tanks could be shipped into Europe from America and Britain.
The designers wanted to create an anti-tank SPG that had a low profile, a powerful gun and that could travel just as easily in reverse as forward. It was to be the ideal ambush weapon that could wait for the enemy to appear in a concealed location then open fire inflicting as much damage as it could before quickly reversing out of danger to its next pre planned ambush location. For survival, the front armour would be thick and sloped.
The production tanks now known as the Broadsword were fitted with a 155mm rifled gun with the gun being able  to elevate from −10 to +20° and traverse +/− 2°, allowing fine tracking without moving the hull allowing the target to be tracked.  a total of 40 rounds were carried in the hull for the main gun and fitting for two machine guns to both the commander hatch and the gunner hatch.
The tanks were withdrawn from service in the late 1980s.




FV4030/3 Chieftain 2
    Also known as "'4030 Phase 3'". The chieftain 2 represented a massive step up in MBT armour when a reshaped hull and turret incorporating Chobham armour with the rear of the hull similar in design to the chieftain 1. The fire control, gun control and automotive systems were also upgraded as was also the command & control, the new No 84 commander's (PPE) day/night sight and laser tracking and ranging system for the gunner.
The project began in 1974 and the first vehicle ran in October 1978. The production order was for 1,200 MBTs and production release given for 250 before cancellation in February 1979 with only 5 completed tanks ready. These were used by the company for several years for various projects until they were all scraped in 2012 when Vickers Newcastle closed.

Well I know the Marksman is real. They actually built a handful of turrets and sold the to Finland, who first used them on T-55 chassis, then put them into storage for a few years, then refitted them to T-72 chassis and put them bakc into service.

The radar in Marksman is basically the same as the set used in the Sea Cobra CIWS system, which had the radar on top of an Italian turret that superfically looked like a Breda-Bofors twin 40mm, but actually carried two 30mm Mauser cannons. Sea Cobra got as far as UK land-based trials in the late '80s and apparently performed decently (which bodes well for Marksman), but never found a customer.

So are the other two, all real world developments.  The FV4030/3 was the Iranian Shir 2 that was never delivered due to the revolution and eventually became Challenger.  The Broadsword was also known as the Jagdchieftain.

Takom do a 1/35 Chieftain Marksman.  The turret was tested on many chassis, good whiff fodder.

DragonBadger models do a Jagdchieftain conversion.  They also do a spaced armour proposal, as well as several real world variants including the Willich AVRE.

I tryed to produce an APC Chieftain... but soviet aethetics kill me.
