Incredible transistors and revolutionary microcircuits

Louisville-Slugger-sized grenade cannons

Jet-powered roller skates (enable an entire infantry to move down the highway at 60 m.p.h.)

Atomic Naval cannons (fire a nuclear salvo 500 miles, revolutionizing battleship power)

Flesh healing serum (closes open wound in two seconds with synthetic liquid tissue)

Alloy for the shell of the S.I. space capsule (resists penetration of space radiation)

Burp-Gun (fires cartridges the size of .50 caliber machinegun bullets--the equivalent of artillery shells--at a rate of 1,000/minute)

Pocket-sized disintegrator ray (installed in a common flashlight case)

A-12 Artillery Transports

The Y-69 three-man rocket

Anti-gravity device (only working model; a ray of an unsafe design, but so powerful it can literally move mountains)

Remote-controlled observer missiles (take pictures of the enemy)

Uranus-11 rocket

Proton anti-armor gun

Moon Missile (which was actually a rocket with the first capsule that could fly independently of the main rocket)

Mangler missile (with a guidance system so sophisticated that it could actually attach itself to an enemy rocket, control it, and destroy it if need be)

One-man mini submarine (a scout sub; can out run, out flank almost any torpedo; compact size gives it great strength per cubic inch)

Sub-miniature reverser

Enervator ray (experimental medical device)

Centrifugal force ray

Rocket sled

Atomic Earth Borer

Tracer shells (capable of tracking and zeroing in on a target)

Anti-missile missile gun

Uranus-12 rocket

Life Model Decoy (of himself and others)

Electric memory bank (a repository where Stark has placed/recorded all of his activities and ideas so Humanity can continue to benefit from his vast knowledge after his death. It contains Stark's lifelong knowledge.)

Light-bending device (installed in a car, makes occupants invisible to those looking in)

Magnetic memory device that channels tractor-pressor beams to reassemble things

Security-Scan (the forerunner of retinal and/or biometric scan)
