The Xindi-Insectoid assault shuttle was a type of shuttlecraft-sized two-person assault vehicle carried aboard Xindi-Insectoid starships. It was armed with a half dozen particle cannons and torpedo launchers. Much of its power was routed to structural integrity, allowing it to operate in the atmosphere of a gas giant or underwater.

The crew found the vessel difficult for a Human to fly; Travis Mayweather likened it to “steering an asteroid-runner with a bad axis coil.” Mayweather and Charles Tucker III used the shuttle to enter the detection grid found in the Azati Prime system and take scans of the Xindi primary weapon. Later, Captain Jonathan Archer flew the shuttle in himself, carrying several photonic torpedoes in an effort to destroy the weapon. He and the ship were captured by Xindi forces. (ENT: “Azati Prime”)
