DESTROYERS have carried a big load in this war. Always versatile, they have taken on jobs of which the naval theorists never dreamed. Read the history of the scrappiest naval-vessel type afloat, which was originally designed as a counterweapon and grew up to be the work horse of seapower.

IT HAS been found that certain rays of about the frequency of those from neon light will kill bacteria. It has occurred to me that probably stronger rays might kill the termites that work so much damage in wooden houses. I also thought that it would be interesting if the matter could be discussed in P.S.M.; then possibly an experimenter would be able to find some way to kill termites at work through several inches of wood.

JAP SUICIDE KILLERS
A veteran war correspondent tells how fanatical hatred and weird rites send pilots of Kami-Kaze Corps to death.

ALLEN RAYMOND
OUT of the depths of savagery and superstition the Japanese have forged a fantastic weapon to hurl at their American enemies by land, sea, and air. It is merely an idea—the glorification of death in battle. The high command of the Japanese armed forces has taken this idea and indoctrinated picked groups of young men with it, so that they deliberately go out seeking suicide in attacks on their Empire’s foes.

NOW we can fully understand why GI tank men “griped” about the General Sherman medium tank when they had to pit their weapon against the German Royal Tiger in their sweep through France and western and southern Germany. Stewart Rouse, POPULAR SCIENCE staff artist, visited the Army’s Aberdeen Proving Ground in Maryland, where he inspected both the 60ton Tiger and the 75-ton Royal Tiger, brought over here for study by American tank experts.

How the Norden Bombsight Does Its Job

VOLTA TORREY
THE Norden bombsight, one of the most fascinating, hush-hush tools used in winning World War II, is both a magician and a mathematician. It creates an illusion, and uses that bit of magic to solve two problems in trigonometry faster than a professor of mathematics could do it.

AN EIGHT-TUBE, stationary rocket launcher that shoots out 4.5-inchers 4,400 yards has been added to American armament in the field. A development of the infantryman’s single-tube launcher (P.S.M., Nov. 1944, p. 79), this new weapon, which is fired electrically, is easily transported and quickly set up by artillerymen moving against the enemy on the heels of the infantry.

SOAPLESS CLEANSER. A new synthetic skin detergent, known as pHisoderm, which cleanses thoroughly and more quickly than soap, has been developed by Dr. B. Thurber Guild, president of Fairchild Brothers and Foster. It is produced in the form of a thick, fluid cream which contains no soap, no fatty acids, no alkali, and no perfume or coloring matter to produce allergy.

AS NEVER before in the history of American wars, wounded men are being returned to civilian life with the scars of battle healed—thanks to the surgeon, the engineer, the craftsman, the sculptor, and the artist. A quarter of a century ago, in the First World War, 46 out of every 100 men who received fractures of the limbs were permanently disabled.

BORING THROUGH HARDENED STEEL is now done with a triangular-shaped drill provided with chip-clearance grooves at its point. No annealing is necessary with the Hardsteel drill, for it works on the principle of annealing the work beneath the drill point by frictional heat, then wiping out the softened chips.

YOU may be held up by a thug. When that happens, you will be glad you studied these pictures. They show how you can out-smart and often overcome a bruiser who makes a surprise attack. It’s science and quick thinking pitted against brute force, and the advantage is likely to be with the little fellow who knows how to meet attack.

THE Army and the Navy have discovered the means of keeping tens of millions of dollars’ worth of military equipment from going up in the smoke of wartime fires. On war fronts from Fairbanks to Accra and from Kwajalein to Chengtu, flames are being quenched almost as they start.

From above, seen against the water, the blue top fades into an almost invisible shadow. If it is hard to find, once discovered, it’s harder yet to keep in sight.

How Armies Hit the Silk
Invented centuries before the airplane, the 'chute was still just a stuntman's toy at the end of the First World War. Now it saves countless flyers' lives, ferries weapons and supplies, and spills airborne troops from the sky to strike behind the enemy's lines.

THE airborne forces that parachuted to earth beyond the watchers on the Rhine this spring mushroomed out of an idea that is older than Uncle Sam. The parachute was invented before the airplane, but, until after World War I, parachuting was mainly a showman’s stunt, on a par with sword swallowing.
