Fwd 2020-11-26 [2.1.0.70] Incorrect Gun Control Speeds - Challenger 1, Chieftain Mk.10


Vehicles Affected:

Chieftain Mk.10, Challenger 1 Mk.2, Challenger 1 Mk.3

 

Description:

Gun control speeds on the affected vehicles are incorrect according to the manufacturer's specifications.

 

References:

 

Current maximum gun control speeds on the affected vehicles:

Chieftain Mk.10

In the mid to late 1970s the Chieftain went through a series of upgrades to bring all marks to Mk.5 standard and then to upgrade all marks further. Part of this upgrade was the installation of a Laser Rangefinder and new Fire Control System known as IFCS (Improved Fire Control System) made by GEC Marconi, this system was later improved for use on the Challenger tank as CSS (Computerized Sighting System) until 1987 when replaced by the ICSS (Improved Computerized Sighting System). The IFCS should therefore be installed on the Chieftain Mk.10; the Challenger Mk.2 and the Mk.3 should have the CSS or ICSS, however the IFCS stats should at the very least be a baseline performance (i.e.: they should not be worse)

Now for the meat, a brochure from Marconi (1977) listing the specifications for the IFCS (relevant pages displayed, the rest are available if required):

As can be see the IFCS has maximum traverse and elevation rates of 400 mil/s (22.92 deg/s). The Chieftain Mk.10 in-game already roughly matches this in traverse at 22.5 deg/s but it's elevation speed of 5 deg/s is well under the specification listed here. The Challengers in-game have a faster traverse rate at 31 deg/s - given it uses a newer system this is to be expected, however the Challengers also share the same elevation rate as the Chieftains at 5 deg/s, it should be improved to at least equal the specifications of the IFCS (22.92 deg/s).

 

Conclusion:

Gun Control speeds on the Chieftain Mk.10 should be adjusted to those of IFCS (22.92 deg/s traverse and elevation), and the speeds of the Challenger 1 Mk.2 and Mk.3 should have the elevation speed improved to meet the IFCS specification.
