...back it up. Bush details the changes in warfare since World War II, and those we can reasonably expect in the future. He describes how light, mobile, powerful weapons such as recoilless guns have swung the advantage in land warfare back to the defense; how the co-ordination of radar net, jet-aircraft, and guided missile should make things very tough for the high-altitude bomber; bow rockets and fast submarines will be advanced enough to chop up conventional naval vessels at long range. Bush tends to describe war as crystallizing into a stable pattern-he states that a future...
...reached the climax of Hiroshima. Dr. Bush thumbs through the catalogue of miraculous instruments of World War II: radar, the eye which helped save Britain during the Nazis' all-out bombing campaign; sonar, the underwater ear which helped break the Nazis' almost-decisive U-boat campaign; missiles, such as the V-i which "might well have stopped the [Normandy] invasion"; rocket-firing bazookas which can stop tanks; recoilless guns which can be carried by two men and have the power of 75-mm. howitzers...
True, high altitude bombers sent against warships "have their limitations. They can seldom see a target on the ground clearly, except by radar." And with "ordinary bombs which fly many miles horizontally as they drop they cannot hit the side of a barn-they cannot even hit a small city with any assurance . . . [But] the guided bomb alters this whole situation ... A great ship alone on the sea is a clear target to radar and a clear target for a guided bomb." Therefore, unless some effective seagoing defense against airborne attack comes along, "the days of the large fighting ships...
...equal or comparable strength, was a delusion, and not worth the extreme cost and effort it entailed . . . [In the future] no fleets of bombers will proceed unmolested against any enemy that can bring properly equipped jet pursuit ships against them in numbers, aided by effective ground radar, and equipped with rockets or guided air-to-air missiles armed with proximity fuzes . . . The days of mass bombing may be approaching their...
...cloudy afternoon last week, twelve B-26 light bombers roared down the runway at Floyd Bennett Field, took off and disappeared to rendezvous for a bombing run on New York City. Minutes later, three radar stations in outlying areas, two manned by Canadians, one by Americans, had picked up the bombers and flashed instructions by radio to eight waiting Canadian Vampire jets and eight U.S. F47 Thunderbolts. "Operation Metropolis," a simulated air attack and defense of New York, was underway...
