I had the chance to do some way cool work on the new Kratos rocket. It's a target rocket for testing a missle defence system. It's based on the old Aries sonding rocket though highly modified. It has to handle Mach 10 (hense the mods). I was tasked with applying the black ablative material to the fins and tail can. GOD I LOVE MY JOB!!! :roll:

The Aires is quite a kit bash. A 4FNC with a X impulse motor!
(~13,000,000 N-s total impulse motor).


According to this photo series https://www.wsmr-history.org/Aries.htm your little old Aries is only a Minuteman I second stage fitted with four fins and a nose cone.

Yea, I was sure to clear it in detail with the company security chief. All images I have were cleared for the company quarterly news letter. He said that being the case it was ok, even for an open forum. Additionally the materials we used are commercially available, applied as per manufacturers specs. Sorry, no technicial drawings allowed.

LOL, this will probably sound like a 1-up but for the next 4 months I'm helping out with the design of a "Z" engine :p
nice, that's way cool.

Mind if I ask who you're working for?

Cobham Sensor Systems Baltimore.:D Just a curious question; I see you're from Phili. What club do you fly with? My wife's from there and we go up frequently. I'd be cool to have a place to launch there.
