The Tiny Tim was built in response to a United States Navy requirement for an anti-ship rocket capable of hitting ships from outside of their anti-aircraft range, with a payload capable of sinking heavy shipping. [1] The Tiny Tim was manufactured using 11.75-inch (298 mm) pipe, which was chosen because it was already being manufactured. [2]

According to the China Lake Weapons Digest, [3] the Tiny Tim was

... designed by the Caltech-China Lake team as a bunker-buster, Tim was the first large aircraft rocket, and, although it saw only limited service in WWII, it helped form the foundations of many postwar developments in rocketry.

The "Tiny Tim" name came from the fact that the drawings of the rocket, which were made without official approval, were presented to the supervisor of the design team in late December. [4]

The Tiny Tim's diameter of 11.75 in (29.8 cm) was the first Allied aerial rocket to have a larger calibre than the Luftwaffe-deployed bomber destroyer aerial rocket ordnance, the Nebelwerfer-based BR 21 of 21 cm (8-1/4 in) calibre. The Tiny Tim's large diameter allowed a sizable 148.5 lb (67.4 kg) semi-armor-piercing high-explosive warhead, some 60 lbs (27 kg) heavier than the BR 21's 40.8 kg (90 lb) warhead. The Tiny Tim had a maximum range of 1,500 meters (1,640 yards), some 200 meters greater than the BR 21's time-fuze limited 1.2 km detonation range from launch.

They were used by the United States Navy and United States Marine Corps near the end of the war during the Battle of Okinawa, and during the Korean War. A problem with the sheer power of the rocket motor causing damage to the firing aircraft was resolved by having the Tiny Tim drop like a bomb, and a lanyard attached to the rocket would snap, causing the rocket to ignite. [5] Common targets included coastal defense guns, bridges, pillboxes, tanks, and shipping. [6] An ambitious operation to use the Tiny Tim against German V-1 sites as part of Operation Crossbow, code-named Project Danny, was planned but cancelled before the squadrons assigned could be deployed to Europe.

Common Tiny Tim delivery aircraft during World War II included the PBJ-1 Mitchell, [7] F4U Corsair, F6F Hellcat, TBM Avenger, and the SB2C Helldiver. [1]

After World War II, the United States Navy's rocket laboratory at Inyokern, California developed an even larger version of the Tiny Tim, called "Richard", which was 14 inches in diameter and one of the largest air-to-surface unguided rocket ever developed for the US military. While tested, it was never placed in production. The United States Navy also experimented with a version of the Tiny Tim which was a two-stage rocket, with another Tiny Tim rocket motor mounted behind a complete Tiny Tim. Like the Richard, it never moved beyond the research and development stage. [8]

During the second half of the 1940s Tiny Tim also had a short civilian life, when it was modified to be used as a booster for the first U.S. sounding rocket WAC Corporal.

Designed as an air-to-air weapon for interceptor aircraft to shoot down enemy bombers, it primarily saw service as an air-to-surface weapon. The FFAR has been developed into the modern Hydra 70 series, which is still in service.

The AIM-152 Advanced Air-to-Air Missile (AAAM) was a long-range air-to-air missile developed by the United States. The AIM-152 was intended to serve as the successor to the AIM-54 Phoenix. The program went through a protracted development stage but was never adopted by the United States Navy, due to the ending of the Cold War and the reduction in threat of its perceived primary target, Soviet supersonic bombers. Development was cancelled in 1992.

The SS.12 and AS.12 are two variants of the same missile: SS for surface-to-surface and AS for air-to-surface. It was designed in 1955–1957 by Nord Aviation, later Aérospatiale. It was a derivative of the NORD SS.10 and SS.11 missiles which were surface-to-surface wire-guided missiles for use by infantry, vehicle or a helicopter primarily in the anti-tank role, but also anti-material, anti-personnel and against light field fortifications. The SS.12/AS.12 was basically a scaled-up version of the SS.11/AS.11, with a massive increase in range and warhead weight. The SS.12/AS.12 original mission was primarily to be anti-shipping from naval helicopters and combat aircraft or ground launchers, and secondarily for use against heavy field fortifications. The range and the destructive power of its warhead are roughly equivalent to a 127 mm (5-inch) artillery shell.

The rocket was developed for both air-to-air and air-to-ground operations. It can be used to carry various types of warheads, including chaff for countermeasures. It is usually fired from the LAU-10 rocket pod holding four rockets.

The NOTS-EV-1 Pilot, better known as NOTSNIK was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS). NOTSNIK began as an in-house project using available NOTS funds. The Advanced Research Projects Agency later supplied some funds for the program. The program involved creating transistorized sensors to detect nuclear explosions from the Operation Argus tests. Ten were launched during July and August 1958, all of which failed. It was the first air-launched rocket to be used for an orbital launch attempt; however, none was recorded as having reached orbit. Following the third orbital launch attempt a NOTS engineer at the tracking station in Christchurch, New Zealand reported receiving a weak signal from the spacecraft; This was never confirmed, and the launches were not catalogued as having reached orbit. The Pilot rocket was part of Project Pilot.
