Beyond the fantastic armor of his vaunted bodyguard, Tony Stark has also built specialized equipment for a number of super heroes including Captain America's early Avengers-era shield. (After installing special magnets and Stark's sub-miniature transistors, the shield could be controlled remotely. Stark also added the most advanced comm. system he could build, integrating it into the shield’s slim profile.) Later he would build a silver shield for The Captain a.k.a. Steve Rogers a.k.a. Captain America, Captain America's later (replacement) shield, U.S. Agent's armor (with gauntlet-mounted photon shields/blasters), Hawkeye's arrows, and of course, the War Machine armor.

Stark has also designed and built numerous weapons and gadgets for the ultra-secret Supreme Headquarter Intelligence Espionage Law enforcement Division (SHIELD), most notably the SHIELD Helicarrier (a massive, one-mile long flying base). Other devices include: Rocket ram; Nick Fury's flying car and pistol; Thermal-shocker Class-A missile interceptor (a tank-like weapon, at the time the biggest gun made, short of an A-bomb); Mandroids.
