Temperature.humidity and airflow can bevaried to create a wide range ofclimatic conditions.The unit makes possible thedetailed and accurate measurementof the effect on the human body ofvarious long term environmentalsituations. Factors affecting life insubmarines on long exercises, forexample, can be reproduced,measured and studied. Many othersituations affecting servicemenand their jobs can be simulated.The SE Labs 5000A. recordersituated in the control room is usedto make permanent records of biophysicalmeasurements fromresearch investigations and allowsthe research team to instantly recalla particular function for detailedanalysis The SE Labs EMMA system,which is sited within the chamber,enables several subjects to bemonitored at the same timeAlthough the EnvironmentalMedicine unit was designed to meetthe Royal Navy's own immediateresearch needs, its wide range ofnew facilities could well producemedical research results of internationalinterest These resultswould certainly be of use to theother Armed Services.

General Dynamics ofAmerica have recently carried outtrials of the Phalanx gun system,which the US Navy is to adopt as amethod of defence against incomingmissiles.The trial firing was made from aship simulator on shore which reproducedthe motion of a ship at sea.The target was towed by a USNaircraft — not quite the sameconditions as a missile attack. Thenext phase is for the prototypesystem to go to sea on board the USSKING and the full weapon system isexpected to come into use in 1976.Phalanx consists of a six-barrel20mm Gatling gun with its own pulsedoppler.search-and-track radar onthe same mounting. The wholesystem stands about 15ft high,weighs 11.0001b and occupies 58sqft of deck space.The radar locks-on to an incomingtarget and the gun. which is slaved toit. follows the target automaticallyand opens fire when the rangereaches a pre-determmed point. Anelectronic spotting device measuresthe angular error of shells whichmiss and automatically corrects thegun's aim.The Gatling gun has a rate of fire of3000 rounds per minute and uses aprojectile with high penetratingpower and hence greater lethality.The US Naval Weapons Laboratoryrecently tested a new shellwhich finds its target by means ofthe reflected energy of a laser beamdirected from another ship oraircraft. A laser receiver in the shellpicks up the energy reflected fromthe target and uses it to steer the projectile.The shell is being developed by theUSN as a joint-service missile for useby both army and naval guns.USSRSSN-8 MISSILESTwo n«w long range submarinelaunchedSSN-8 missiles wererecently tired by the USSR over arange ot 4000 miles, with their singlewarheads impacting in the Pacificabout 500 miles north of MidwayIsland. Reporting this on October 3.Pentagon sources said the firingswere believed to have been madefrom a new Delta-class submarineand that the range was more thantwice that ot the longest-ranged USsubmarine-launched missiles. TheSoviet now has f.ve of the new Deltasubmarines operating, with anotherfive in the final fitting stage. Only thetwo missile firings were observedbefore TASS announced theconclusion of the tests.CONTRIBUTIONS INVITEDThe editor Invites persons to submit articles, photographs and drawings (Mack Ink) torInclusion In the magazine, but regrets that no payment can be made for contributions submitted.Contributions should be addressed: The Editor "The Navy", Box C178, Clarence StreetPott Office.
