Recently I've been preparing some new loadouts for the CAC Sabres, which include the RP-3 No.1 Mk 5 rockets. I had bugger all info but after some research, uncovered that the stock RP-3 were incorrectly modelled. The default RP-3 is woefully undersized and undermodelled. It is quite a heavy rocket and much larger than people think. It is now the correct lenght (original 1.4m total, now 1.4m for body + 20-40cm for warhead). Weight increased, burning time adjusted with more power, calibre corrected etc. Now it actually flies like a RP-3, not a HVAR which it was a clone of . Whilst at it, I've added in a few more models, the 25lbs AP and 25lbs Anti-submarine (similar but with a slightly different head). And for course for 1956 project, I've made the Mk 5 60lbs and 25lbs AP. The Mk 5 appears to have different fins, a new attachment system and by reading about the Mk 4 motor, a more powerful motor than the WW2 variant.
Here are a few pics. The difference between stock is noticable, but now it is the correct dimensions. The 25lbs AS head is longer than the 25lbs AP head. Also note just for preview sake, the smaller fins on the Mk 5 AP shown at the bottom:




Here is a quick little beta. To test out all the rocket types, I've updated the Mosquito Mk VI Costal Command (available in DBW or separately). Note that whilst both 25lbs rockets are considered 'armour piercing', the 2nd one (25lbsAS in the loadout) has a specialized 'anti-submarine' warhead.
Let me know how you go and if everyone likes the changes, will include them in the next DBW.
