Does this look right - re Chain Gun & Cannon

I got some stats re the weaponry used on several British AFVs and I found the rate of fire of both a bit surprising - does this look right to you - it seems low to me -

Main Armament
Rarden Cannon (30 mm) Maximum rate of fire: 50 rounds per hour

Approximately 201 x 30 mm rounds in clips of 3 are carried

Co-axial Machine Gun (7.62mm L94A1 Chain Gun)
Rate of fire rapid: 120 rounds per minute

Came from here -

which should be accurate.

 

The Brits do slow down the rate of fire, comparatively, to increase the consistancy of their weapons. However, they are not that slow. I suggest you take a look at some other web sites for the correct answers

 

IIRC the Rarden Cannon is single-shot, not automatic.

 

Even so a ROF of less than a round a minute seems excessively slow.

 

Per hour!

I had not seen that - should it not be per minute?

 

Probably per minute. IIRC Rarden was designed for single-shot accuracy rather rate of fire, but has a 3-round burst capability.

 

I've emailed the British Army Web Editor and asked him to check this info.

 

Just found this video of a Warrior on another part of the British Army web site -

Both the chaingun & cannon are demonstrated and I would estimate the chaingun is approx 500 to 600 rounds per minute and the cannon fires 5 rounds in about 4 seconds but that would not reflect its true rate of fire as it requires frequent reloads. Both though are much faster than the figures above.

 

The Rarden L21A1 gun on the Warrior has a cyclic rate of fire of 80-90 rounds per minute.
The 7.62mm MG L94A1 has a rate of fire of 520-570 rounds per minute.
