We don't hear much - if any - talk these days about a certain weapon type being a 'peace maker,' 'game changer,' or a 'stale mate proposition.' That is because most nations, or for that matter terrorist groups, have access to some ferocious weapons. The world has operated for a long time on the Mutually Assured Destruction (MAD) principle, where skirmishes have been fairly local. Many conspiratorialists as well as arguably rational people believe the real game at hand is Mutually Assured Financial Destruction (no clever acronym for that one), where world financial powers cooperatively trade off monetary wins and losses via what was termed by President Eisenhower the 'Military-Industrial Complex.' You don't need to be one who wears a tinfoil hat or keeps your saving buried in a jar in the back yard to suspect at least some form of malfeasance is going on at the expense of us 'little people.' ... but I digress. This editorial that appeared in a 1944 edition of Radio-Craft reports on the "recent reports" of radio-controlled rockets and missiles that can be steered with precision to their targets after launching, rather than relying entirely on expert ballistic predictions that depend on variations of propellant, aerodynamic surfaces, wind, atmospheric pressure, etc. Cruise missiles and more recently drones come to mind as the perfection of such a weapon. Terrorists cells might still have difficulty obtaining and deploying a cruise missile, but drones capable of delivering highly damaging explosives - conventional and nuclear - can be bought in hobby shops and online from catalogs. Given that reality, it might be time to trade your tinfoil hat in for a pith helmet. Come to think of it, with Ebola virus victims being brought into the country, and respiratory virus (and otherwise) infected illegal aliens being given free passage across the Mexico border without health checks, maybe a Hazmat suit would be most valuable.
Future Radio Rockets
May Be World's Most Terrible Weapons
The recent reports of radio-controlled, rocket-propelled explosive missiles mark the first practical appearance of an instrument, which - no matter how imperfect, ineffective or inefficient it may be at present, is destined to be the most dreadful weapon ever devised, and perhaps the most terrible weapon that ever will be invented.
There are many who are contemptuous of the rocket as a serious weapon. Their attitude is based, no doubt, on the fact that it has been known for a long time. Never, up to date has it been able to perform all that was expected of it.
Such an attitude is dangerous, for should the rocket suddenly appear in a form commanding respect, it will be much too late to do anything about it. It is not unusual in technical matters for the perfection of a device to be held up until something else, apparently quite extraneous, has been developed. For example, the modern machine-gun was impossible until the brass cartridge case could be manufactured in quantities with precision, and that depended on development in precision engineering, particularly in presswork.
In the case of the rocket, early experiments and even practical uses, up to recently were no more than demonstrations that rocket-propulsion does actually work. That form of propulsion has not yet been developed in practical uses to anything like what is possible; for instance, explosive propellants can be used much more efficiently in a gun than in a rocket. The full power of the rocket as a weapon could not be attained without some of the most recent scientific developments, particularly in radio.
Rocket and Target Speed
The maximum speed of targets on land and sea may be taken at 60 miles per hour (88 feet per second), and if the average velocity of gun projectiles is taken as 1,500 feet per second, then the latter is about 17 times faster than the former. Taking the average speed of modern airplanes as 375 miles per hour (550 feet per second), the projectile is less than three times faster, and if the airplane is at a high altitude the projectile may be less than twice as fast, hence the comparative immunity of aircraft. To restore the ratio of 17 times relative to aircraft, missiles must have a velocity of 9,350 feet per second.
Rockets with good directional stability may therefore deprive aircraft of its present immunity without using radio-guiding. With such guiding, - even at velocities of 1,500 to 3,000 feet per second, aircraft would have little chance of escape, that is, if the radio control is really effective. The radio-guided rocket-propelled explosive missile is indeed a super-weapon, a spear which can be thrust into any part of a country's anatomy at will and against which there can. be no adequate defense other than counter bombardment with the same form of missiles. It is a delusion to think that some ready antidote can be found, comparable to degaussing against magnetic mines, which will render the radio-guided missile ineffective. No such antidote has been found for a bullet in hundreds of years.
Equally useless is the wishful thought - based on the crazy antics of unstabilized experimental rockets - that rocket-propelled missiles will be as dangerous to the senders as to the receivers, for with proper radio control such erratic behavior disappears. The idea that one need only switch on a radio transmitter to take over the control of an enemy's missiles and thus turn them on him or render them innocuous is absurd. In this war radio is used universally, even in the front line, giving plenty of opportunity for radio tricks, but how effective have such tricks been? Ordinary broadcasting has not been seriously impaired by jamming, or even the imposition of the death penalty.
Manual Control Impossible
The present is not time for discussing the principles of or systems for radio-guiding high velocity missiles. Certain it is that the latest developments in radio, radiolocation, remote control and automatic devices, will be required. Radio controls such as have been used for steering model airships around a theater; or target airplanes, are out of question. It is difficult enough for a pilot sitting in a high speed airplane to guide his craft so that it will ram any given target. The idea that any man by his own manipulations of radio apparatus can accurately guide a missile he cannot see and the immediate position of which can only be indicated instrumentally when that missile is travelling at anything between 1,500 and 7,500 miles per hour is ridiculous. The speed of human reactions and of human reasoning is far too low. The actual control while the missile is in flight must be entrusted to automatic apparatus, apart from secondary controls which are within-the powers of-human manipulation.
The -perfected radio-guided rocket-propelled missile has not appeared yet, but it is something to be treated with profound respect. Delay in taking steps to meet it will be, to say the least, most unwise. There is no reason why this country should not perfect the new weapon first, but it is not one of these cases where the spade-work can be left to others, with the idea of taking it up when it has been fully proved. The position is more like that of two men grabbing for the revolver on the table. The one who gets hold of it first will be the sole survivor. An obvious first step is to find and obliterate places where the weapon is being developed or manufactured for use against this country, and the last step, necessary if others fail, is armor protection and plenty of it, as in deep shelters and acceptance of such changes as are necessary in becoming permanent troglodytes.
In one respect the new weapon, dreadful as it is, may be of the greatest benefit to man, by producing the final stalemate in war. The service personnel required to man the defenses of a country, that is, the launching cradles, will be such a small number that any country may be permanently mobilized. Its power in war will depend on its stock of missiles and the rate at which it can produce them.
The stock of missiles will be the unknown or uncertain factor, and a country can be at war in full blast in a matter of hours if not or minutes. One false move by any nation and all hell is likely to break loose in less than no time.
Under such conditions ideas of conquest or stealing a march on other countries are out of question, for the situation would be like that of a small village in which the occupants of every house are fully armed, in position, with rifles aimed and all suffering from trigger-itch. Under such conditions life could not go on without full mutual confidence and understanding. It would be obvious to every country, whatever its lust for power and dream of conquest might be, that there were far more chances of gain in arbitration than in the certain destruction which would inevitably accompany armed combat. When that happens the radio guided rocket will take its place alongside the passenger-carrying airplane as a means of rapid, automatic transport for mails and perishable or valuable goods.-Aeronautics (London)
