Wondering if there are any decent, on-line sources for NATO/US and Soviet/WP, Cold War tank gun shells, ballistic data? Looking for date(s) of availability, penetration at various ranges, accuracy (if available), etc.. |

I'd be surprised to find real numbers for any of the 120mm shells, as they're likely to still be classified. 105mm NATO is likely to be more readily available, I don't think there has been any major development in a good 20 years. Manufacturer's sales brags are likely to be available, but it's anyone's guess how accurate those are. Penetration numbers will almost certainly be manufacturer's sales brags. Dispersion numbers are almost certainly classified, but a decent rule of thumb I've found is ~1.5 minutes of angle (roughly 0.5mils). Some rounds may be better, some may be worse, but for general work 0.5mils seems to be pretty good. |

Thanks for the links and info. Some of those are really great! Looks like the Soviet 100mm HEAT round was introduced in 1958, with a penetration of 380mm, for the T-54/55s. The US 90mm got HEAT in 1950 (possibly earlier, from WWII), with a penetration of about 220mm (one reference mentions 250mm) – M348 round. Later, it appears the M431 round became available in 1956 or so, and had a 320mm penetration. Both were used in the M47 and M48, and the earlier one was used in the M26 and M46 (not sure if they got the later one). I suspect the West German Jagdpanzer Kanones used the latter round too. There's also mention of another 90mm HEAT round coming out around the late 1960s (1968?), with a penetration of around 380mm – 400mm. Not sure about that one, but I guess it could possibly be a later variant of one of the previous two mentioned. Would love to verify that, but haven't been able to thus far. Possibly an A1 or A2 variant of either the M348 or M431. Some also mention rounds with a "T" series heading, e.g. T300. Would also like to know if the West Germans got it for their JgPz Kanones. Seems likely if it was indeed a real round, since they were still fielding M48s back then (and possibly M47s too), around that time period. |

I can't find a source, but I seem to recall that the 400mm penetration might be a Belgian round. |

Thanks, might make sense, since they had the Jagdpanzers too, plus some older 90mm American tanks, IIRC. Any idea on availability date for it? |
