The Piper LBP was a glide bomb, or "Glomb", developed by Piper Aircraft for the United States Navy during World War II. Developed as one of three "Glomb" aircraft, the inherent limitations of the Glomb and the technology of the time, combined with difficulties encountered in testing of the prototype, led to the production contract for the LBP-1 being reduced, then cancelled, with none of the Glomb aircraft ever seeing operational service.

Design and development

During late 1940, a proposal was made to the United States Navy outlining a concept called "Glomb", for "glider bomb". The Glomb concept called for the construction of inexpensive gliders that would be remotely controlled from another aircraft to carry bombs to a target, thus reducing the risk to aircrew. [1] Glomb was intended to be towed by an ordinary carrier-based aircraft to the area of the target, where it would be released; guidance following release would be provided via a TV camera located in the nose of the glider, which would transmit its signal to a piloted aircraft, an operator then using radio control to steer the Glomb to its target. [2] Following consideration the Glomb concept was deemed to be potentially feasible, the project was given official status by the Bureau of Aeronautics in the April 1941. [1]

Initial trials of Glomb involved conversions of existing gliders to remotely controlled status; these tests showed that the concept had promise and following a design competition, three companies were awarded contracts to develop operational "Glomb" aircraft. These contracts were given to Pratt-Read, Taylorcraft, and Piper Aircraft. Piper's design, designated LBP-1, was a conventional high-wing monoplane, fitted with tricycle landing gear, and intended to carry 4,000 pounds (1,800 kg) of bombs. Although the LBP-1 was fully capable of being remotely piloted via its TV-and-radio guidance system, it retained a cockpit, allowing the aircraft to be flown by a pilot on board for training and evaluation. [1] [2]

Operational history

Although the initial contract awarded by the Navy called for the production of 100 LBP-1 Glombs, continued trials of the concept indicated that the glider's inherent low performance, combined with technical issues with the television guidance system, made the concept operationally unworkable. As a result, the LBP-1 production contract was reduced to only 35 aircraft in early 1945. [1] In June of that year, the LBP-1 program was terminated, the aircraft having been determined to have dangerous characteristics when attempting landing at loaded weights. [3]

The SSM-N-8A Regulus or the Regulus I was a United States Navy-developed ship-and-submarine-launched, nuclear-capable turbojet-powered second generation cruise missile, deployed from 1955 to 1964. Its development was an outgrowth of U.S. Navy tests conducted with the German V-1 missile at Naval Air Station Point Mugu in California. Its barrel-shaped fuselage resembled that of numerous fighter aircraft designs of the era, but without a cockpit. Test articles of the Regulus were equipped with landing gear and could take off and land like an airplane. When the missiles were deployed they were launched from a rail launcher, and equipped with a pair of Aerojet JATO bottles on the aft end of the fuselage.

Unmanned aerial vehicles (UAVs) include both autonomous drones and remotely piloted vehicles (RPVs). A UAV is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. In the twenty-first century, technology reached a point of sophistication that the UAV is now being given a greatly expanded role in many areas of aviation.

Project Kingfisher was a weapons-development program initiated by the United States Navy during the latter part of World War II. Intended to provide aircraft and surface ships with the ability to deliver torpedoes to targets from outside the range of defensive armament, six different missile concepts were developed; four were selected for full development programs, but only one reached operational service.

It was the most successful of the United States Army Air Forces Jet Bomb (JB) projects during World War II. Postwar, the JB-2 played a significant role in the development of more advanced surface-to-surface tactical missile systems such as the MGM-1 Matador and later MGM-13 Mace.

The type saw some service in the Pacific Theater against the Japanese, but continuing developmental issues affecting the aircraft, along with the success of operations using more conventional weapons, led to the decision being made to cancel the assault drone program in October 1944.
