cobrabase Posted March 1, 2016 Share Posted March 1, 2016 I am correct in that the Abrams cannot fire over the rear engine deck right? 0 Quote Link to comment Share on other sites More sharing options...
Moderators Volcano Posted March 1, 2016 Moderators Share Posted March 1, 2016 There is a back deck clearance switch which causes the gun to elevate to avoid hitting the rear. When this happens the gun cannot fire, however you can fire if the gun is elevated above this. So... yes and no. 0 Quote Link to comment Share on other sites More sharing options...

It's never the safest to fire sabot over the rear because of the "petals?" 0 Quote Link to comment Share on other sites More sharing options...
Gibsonm Posted March 1, 2016 Share Posted March 1, 2016 Well the petals normally discard a little further out.Certainly firing Canister might be problematic. 0 Quote Link to comment Share on other sites More sharing options...
cobrabase Posted March 1, 2016 Author Share Posted March 1, 2016 I heard about a chance of debris being sucked into the intake if fired to the rear. You'd be aiming into the sky though. LOL. 0 Quote Link to comment Share on other sites More sharing options...
Damian90 Posted March 1, 2016 Share Posted March 1, 2016 I think it's exaggarated, especially considering very solid steel mesh protecting air intake and also placement of air intake, and in the end also the fact how massive are air filters for the gas turbine.So what Volcano said is the only limitation.There is actually a lot of urban myths about M1, it's gas turbine and so on. 0 Quote Link to comment Share on other sites More sharing options...
cobrabase Posted March 1, 2016 Author Share Posted March 1, 2016 You got that right about the myths! These two pinheads got on my case when I told them that you can't engage ground targets over the engine deck. Oh... they know EVERYTHING! I'm the biggest moron on the planet!!! Whatever.... I KNEW you can't shoot at anything directly behind you in the Abrams because SB Pro models it so well. I had lost all mobility from an RPG strike in a scenario. I had a T-72 rolling behind me showing me his flank. I had a perfect shot on him and I couldn't make it because of the engine deck switch. I'll remember that moment always. LOL. Nothing I could do. A friend of mine in Colorado served as an Abrams driver and gunner. He told me that when those sabots fly only Sir Isaac Newton can tell you where they will end up. 0 Quote Link to comment Share on other sites More sharing options...
Damian90 Posted March 1, 2016 Share Posted March 1, 2016 I think it's general problem of any western type, mainly beauce of raised engine deck. It could be fixed by raising the whole hull, however this means also more weight for hull, so it's unfortunate trade off. Unofortunetaly tank designing is not easy, lots of trade off's needs to be made. 0 Quote Link to comment Share on other sites More sharing options...

Damian90 Posted March 1, 2016 Share Posted March 1, 2016 Aye, tough interesting fact is that soviets would probably choose something similiar to the engine deck design for some of their future tank projects in 70's and 80's. Object 490/490A "Buntar" had engine deck raised in similiar way to M1 or other western tanks. 0 Quote Link to comment Share on other sites More sharing options...
cobrabase Posted March 1, 2016 Author Share Posted March 1, 2016 Looks like T-80 road wheels. 0 Quote Link to comment Share on other sites More sharing options...
Damian90 Posted March 1, 2016 Share Posted March 1, 2016 There were several variants for Object 490/490A "Buntar", similiar in case of Object 477/477A "Boxer/Molot" and Object 477A1/A2 "Nota", some used T-64 components, some used T-80 components.These projects were what I think you guys in US called FST-2 or FST-3. 0 Quote Link to comment Share on other sites More sharing options...

Members Ssnake Posted March 2, 2016 Members Share Posted March 2, 2016 Well the petals normally discard a little further out.Certainly firing Canister might be problematic.I don't think so. The muzzle extends beyond the edge of the rear hull, and canister flies only in one direction from there... 0 Quote Link to comment Share on other sites More sharing options...
Damian90 Posted March 2, 2016 Share Posted March 2, 2016 Actually question about air induct is interesting, I mean, it does not mean something won't be sucked there, but the actuall question is, when it can eventually happen.And air intake is in such case pretty far from the main gun muzzle. 0 Quote Link to comment Share on other sites More sharing options...

Moderators Volcano Posted March 2, 2016 Moderators Share Posted March 2, 2016 It's never the safest to fire sabot over the rear because of the "petals?" AFAICR, the reason you cannot fire if you trip the back deck clearance switch is because the gun is no longer aligned with the GPS. Probably not a great idea to fire a maingun round such a situation, so it is prevented. 0 Quote Link to comment Share on other sites More sharing options...

Soldiers tend to spray the air induct system with a lot of water which then will cause a blown engine. Actually seen 3 engines blown at the wash rack just in one company. 0 Quote Link to comment Share on other sites More sharing options...
Grenny Posted March 2, 2016 Share Posted March 2, 2016 Has the M1 the ability for deep-fording or snorkel operation? 0 Quote Link to comment Share on other sites More sharing options...
Gibsonm Posted March 2, 2016 Share Posted March 2, 2016 Yes - well at least the USMC variant./jDWgK5HZz4w 0:20: Shows fording kit attachment at rear and pipes on turret bustle prior to fording.1:59: Fitted.3:39: Fully configured - getting wet. 0 Quote Link to comment Share on other sites More sharing options...
Grenny Posted March 2, 2016 Share Posted March 2, 2016 Nice. Our version goes like this(love the silence when the tank is submerged): But I guess a turbine would suck the TC in too :-P 0 Quote Link to comment Share on other sites More sharing options...
Gibsonm Posted March 2, 2016 Share Posted March 2, 2016 Yes, I've done "deep fording" in a Leo AS1.Had a very U Boat conning tower feel to it.Talking to the Gunner and Loader afterwards, they were less enthused. 0 Quote Link to comment Share on other sites More sharing options...

Damian90 Posted March 2, 2016 Share Posted March 2, 2016 Did they get wet?You'd think a tank was a sealed environment, wouldn't you?When I talked last year with our Leopard 2A4 crews about deep water fording they said such excercises are rare due to several reasons, among them were complains about driver hatch not being watertight, and in general water leaks through his hatch.No problems with Leopard 2A5 drivers hatch tough, or at least as far as I know. 0 Quote Link to comment Share on other sites More sharing options...
