I can do tech descriptions.

Anyone can.
"All information on this ship are classified Level Omega, accessible only by personnel immediately authorized by GTVA command."
or
"We do not know much about this ship. It is known however that it possesses superior firepower to our equivalent."
or
"The <insert ship here> is a familiar foe to GTVA forces. It is much like the <insert another ship here> but it has demonstrated a higher top speed/bomb capacity/survivability/payload/blahblah."
I did a tech description for the GTF Snail.
XSTR ("The Snail is infamous for its trails of deuterium waste it leaves behind. One of the weakest fighters in current service, they were originally put into service when there was a shortage in the GTF Slug class fighters. Although it has heavier armor than the Slug, it is notoriously pathetic when it comes to agility. Pilots are not encouraged to fly the Snail( ; ) Slug fighters are the class of choice to any fighter pilot who is authorized to fly them. The true reasons behind the Snail's developement are Classified Level Omega by Terran Command. It has been denied on multiple occasions that the Snail was commissioned to kill off the pilots who would fly them. The successor to the Snail, the GTF Escargot is currently in production at God and Nature Industries.", -1)
