The Sunbird missile looks like a 'ripoff' of the real-life Sunburn/Moskit missile. The Thunderbird is like the Club missile, right?
Rip-off... Wonderful. Just because it looks like something doesn't mean it's a straight copy. There are quite a few designs popping up all in a similar configuration.
The Thunderbirds are actually based off of my original standoff missiles. Propfan powered (at leas the two longer range ones, the ASROC analogue is rocket powered).
Impressive parts sheet.
Thanks, still more to come throughout the next couple of days I imagine.
