Bofors Gun Query

If you log onto http://www.youtube.com and type in “40mm Bofors Gun” you will find a very interesting film showing British troops test firing a 40mm Bofors gun during WW2.

My query is this. The gun in question has a Bren gun fitted above the barrel of the Bofors ,which is shown to be fired along with the main gun. Was this fitted for “spotting” (as in the Hurricane IID which retained two 0.303 Brownings in addition to its two 40mm guns) or was it there just to add some additional AA firepower?

On Topic. I thought the mounted gun was for a local defence for the gun ie ground attack to your potition and very low flying AC where the Bofors would be completley useless.

I doubt that very much. The Bofors was actually pretty good at short range, and in any case it would have been far better to put the MG on a separate mounting so it could be rapidly swung around by hand rather than cranking away at the handles on the Bofors mounting.

Hi Colin, slightly off topic, were you once in the music biz?

Aye and give the troops a real stopper again. At a push I’ll settle for 7.62 as opposed to .303. They always reckoned that at 100 metres you were wasting your time hiding behind a brick wall as 7.62 would punch straight through it anyway.

I think you will find that it was the Chieftain tank that used a burst of three .50″ cal tracer slugs as a ranging device for the 120mm main armament. Nowadays with the improved ranging systems fitted to the big boys and the incredibly flat trajectory of the armour piercing shot of the 120mm, the .50″ cal machine gun is not used in that role. the 7.62 mm coaxially mounted MG is used for soft targets, the roof mounted 7.62mm being for ‘air defence’.

Correct, they now use laser sights.

I may be wrong in what Im about to say, but, Challenger 2 tanks use a 7.62mm GPMG as a spotter so based on that I would say yes its a spotting weapon with the added benefit of extra AA firepower and in my own experience of firing an 84mm Carl Gustav AT weapon which had a single shot sighting “rifle” attached to the side of it. Thats my view, if Im wrong then I look forwards to being corrected and educated in this piece of history. Bex

I suspect that it may have been fitted for low-cost practice with the sighting system (Bofors ammo was expensive..). This is quite a common practice even today. The trajectory would have been too different from the 40mm rounds for it to be used for sighting in combat, and the effective range of the .303 ammo was too short.
