Hi Kurfürst, it's been a while!
I assume those values are at terminal velocity? And at optimum strike angle (60-75 degrees)?
Unfortunately, Hahn does not give any more details than what has been posted. There are of course many variables, ie. bombs released from dive bombers would have higher speed and penetration than those released from level bombers.
At any rate, anything below capital ship class would be vulnerable to these bombs. Even BBs are at a certain level of danger, a while the bombs would be generally unlikely to penetrate the main armoured deck, they could well find their way into the ship's upper works, given the relatively thin armour found at the top, and of course, to hits occurring to the rather sizeable, un-armoured area outside the citadel.
Some more information from Hahn, regarding the rocket-assisted armored piercing anti shipping bomb of the Luftwaffe. These were based on the standard AP bomb designs, and received additional speed boost from an added rocket engine.PC 500 RS "Pauline"
. Rocket engine increased impact velocity by 160 m/sec to 345 m/sec, and armor penetration increased to 200 mm armor. When released from level flight at 3500 m, the bomb could still penetrate 190 mm of deck armor.PC 1000 RS "Pol"
, produced in large quantities (4000+) as well. Hahn describes the effect on a HMS Dido class cruiser in the MTO, after an impact velocity of 1152 km/h, delayed fuse of 0.065 sec.
The PC 1000 RS that hit the cruiser passed through the entire ship, and detonated 5 meter under the keel.
Hahn also gives some details of the measure of operational success guided, gliding anti shipping bombs of 1400 kg Fritz X
and 500 kg HS 293
, by II and III Gruppe of KG 100's with Do 217s.
65 missions were flown with 487 sorties in total. Of these 313 made conctact with the enemy and launched its ordonance. Of the 319 gliding bombs launched, the flight of 215 could be observed clearly. These achieved 65 direct hits, 40 near-hits and 71 further away from their targets; the results could not be observed for 38 bombs.
In total the following results were achieved:Sank
1 AAA vessel
10 merchantmen (76 000 tons)
3 smaller vessels
29 merchantmen (215 000 tons)
1 "Geleitboot" (pilot?)
Regarding the Royal Navy's losses in Dunkerque operations, authors seem to differ in the numbers (ie. I gave figures via Hooton), nevertheless, the results were that the Royal Navy lost apprx. 60% of the destroyer force it committed to the operation within a short timespan, during which it was exposed to the dedicated attention of the Luftwaffe
