An RPG round weighing several pounds arriving with a velocity of 2-300 m/s has quite a bit of kinetic energy to apply, and all of it concentrated at the point of the nose which is usually less than an inch across... and once the point breaks through, it takes far less energy to widen the hole than it would to create an instant several-inches wide breach.
[TomB] That's a good point too. I'm thinking about trying to force several inches in diameter through a hull that can take the sizable sea forces, but the contact point is a fair bit smaller. >Get it off angle and it'll reflect off it does not detonate. Don't bet too much on that. Several types of RPG rounds - I'd expect all of them, but don't know that for certain - are equipped with a biting edge to ensure that they don't glance off even if they hit at quite acute angles... and while those biting edges are there to increase the chances that the round will detonate successfully, they also greatly improve the rounds' chances of smashing through thin obstacles if they fail to detonate properly. [TomB] Really? I've handled several of these (RPGs) and I don't ever recall noticing that. I do know that we used to have our M-72 rockets bounce off the ground, terrain, obstacles, etc. If you got a good face on impact, you got the detonation, but it seemed like if you didn't get a good shot with the M-72 or the Carl Gustav, you could get a skipping miss. That's what I saw on the range, whether this is typical of today's rounds is a whole other story I suppose. >[Tomb] True enough. But if I can match your course at a distance of 15' >in a motor launch ...you'd better pray that you are inside the round's arming distance so it won't detonate (or that it is a dud, giving the same result), because if it does go off you'll get killed yourself when the round's rocket booster, fin assembly and all other parts located behind the warhead come back at high speed and hit you in the face. [TomB] Okay, call it 50' then Mr. Picky. At 50', I'd imagining you are outside of a dangerous launch distance. And the 34' keelboat's side isn't going to be a hard target at 50', even manouvering, because your launch is faster and more manouverable if it is driven by anyone who knows what they are doing. -- "Now, I go to spread happiness to the rest of the station.
