 Only Churchill knew that all was not quite as practical for general use as it appeared. Proximity fuse Professor Lindemann rightly realized that, without radar, the biggest errors in AA firing were in the range direction. He decided to attempt to produce a proximity Page 9.

 The delivery of chemical weapons by ballistic missile also requires sophisti- cated technology such as a proximity fuse to detonate the warhead at the proper distance from the target, and a burster charge to disperse the chemical agent.

 During World War II Mindlin served the government at the Applied Physics Laboratory of the Johns Hopkins University where he lead a team which designed the firing element of the first proximity fuse, a very important device in the war. 

THE DEVELOPMENT OF ROCKET-PROPELLED TORPEDOES

 The greatest risk to successful development was assessed to be the acoustic proximity fuse, and practical work to prove its feasibility was immediately started.  These vehicles were prototypes for a future anti-torpedo torpedo but without the warhead and acoustic proximity fuse.

 The details of the Proximity Fuse were secret-the greater picture only declassified sub- stantially by 1976.[6] A prewar idea, it took the team of scientists, engineers, and radio amateurs at Section T to make a Proximity Fuse work, even though the British had worked feverishly

 This fact was withheld from the American public through censorship for morale reasons at the time, and was never subsequently publicized.) The US was able to catch up with the Japanese, and eventually, with the development of the proximity fuse, to dominate the skies

 I remember how impressed we were by Tuve's speed in building a team of 150 physicists and engineers to create his true radar proximity fuse. I believe that he took not more than eighteen months from initiation to operation. 

Measurement Technique for Sea Height of Burst Using Image Recognition

 When the proximity fuse bursts, light, heat, burst sound and flames occur for a very short time and water poles are formed, because the fragments of the projectile spread out on the sea surface simultaneously.  The burst image of the proximity fuse shown in Fig

 In the course of the war, OSRD directed the work of 30,000 people, including, by one estimate, two-thirds of America's physicists, and was responsible for the development of some 200 weapons, including sonar, radar, the proximity fuse, and the Norden bombsight.
