to knock out armour, what we need is a variety of heads for the rockets...i was reading about US aerial rockets a few days ago@the library (looking for info in tiny tim). on othe the books i looked in had many pix of F4Us w/ rockets. they used a variety of them for different purposes: 3.5" ARs (Aerial Rockets) 2.75" SCARs (SubCaliber Aerial Rockets) & 5" HVARs (High Velocity Aerial Rockets). the rockets could be fitted with different heads. for armour they had a 6.5" armour piercing shape charge head that went on the HVARs. That should do the job on the Tigers...406th FG's web site says HVARS "...rang the death bell for the enemy Tiger tanks..."
SCARs would be nice for taking on field flak (not as heavy, so you could dogfight better with them under your wings)...there were proximity fused HVARs & ARs too...
