Radar Secrets (1940s)

[Music] secret weapons radar what would you have given to have seen these pictures in time [Music] you the world's enemies you who destroyed the peace had you known these secrets before we did you might have won the war but you failed and now we can tell you why you failed we can tell you some of the things you wanted to know we can tell you the secret of why your Destroyer nzuki failed to return to Kula Gulf on the night of July July 6th 1943 one of our ships saw you yes 6 mil away in the dark we saw you how by radar electrical pulses transmitted with a speed of light picking up Echoes from the Nuki in the Fire Control director Men at Work watching small screens that pip that's your ship range for the guns accurate within 10 yards another operator gets the bearing he matches those Pips by turning the entire director the guns automatically follow information goes to plot more train men more machines enemy course 091 speed 12 knots wind 265 velocity 8 knots in Fire Control with in in a minute they know all they need to know about your ship commence firing commence firing the first Salvo a direct hit that's why you never heard from the nzuki again radar how did we get such a weapon at home we had thousands of scientists at work our best electronics Engineers with unlimited resources and only one objective to develop radar superior to yours in radar schools thousands of men were trained to become expert operators it cost us hundreds of millions what did it cost you who once dominated the Pacific and you who submarines almost won the Battle of the Atlantic what happened why was the night no longer safe for your your submarine how could our bombers find them in the dark the secret radar this scope is a map of the surrounding ocean with our plane in the center see that dot that's your sub the technique is simple the radar sights the target then guides the pilot in for the kill starboard steady starbo one mile starboard starboard at half a mile away another secret weapon the Airborne search [Music] light it cost us Millions to know that secret what did it cost you Nazis not to know it and we had other expensive [Music] secrets and you have heard of our greatest secret from such plants as these at a cost of $2 billion the atomic bomb now we are telling you some of our secrets why because today's weapons would not be good enough [Music] tomorrow because already we're working on New Uses for Atomic power on New on Secrets remember you who dream of world Conquest never again will we be caught unprepared remember how we United for war we all had a part we all configured it [Music] take it easy fellows take it easy while you can combat information center is alert its Radars probing The Darkness ready to give early warning of any unseen [Music] [Music] enemy con combat raid able bearing 344 range 358 you got that yet coming right up Sir course 139 Speed 3 0 course 139 speed 30 combat this is KH give me a course to arrive 6,000 yd 40° on the starboard bow of leading ship of R AEL over this combat Wilco out did you get that Ken yo 6,000 y 40° on starboard Bell Speed [Music] 3 course 005 time 12 minutes on this is combat course to attack Point 05 attack point in 12 minutes over Roger prepar to fire five D depth setting 6 ft action starbo over this is combat Roger out stand by for surface action in the gun director the Fire Control radar goes to work enemy Force at 35,000 yd bearing 344 course 139 speed 30 fantastic but radar tells us all this with radar our ships can see through smoke through fog through Darkness radar puts a finger on the Unseen enemy lets our guns reach out to destroy him before he even knows we're there R aable bearing 349 range 108 2 minutes to attack Point time Combat 2 minutes to attack Point Mount one train out the starbo match pointer us we can launch Torpedoes any time now but the closer you get the better though you can wait too long [Music] what do you make of it hard to tell sir two large Pips and one smaller one range on the nearest large control combat Target able looks like two Cruisers and a destroyer range closing all guns load gun one gun two gun three gun four gun five we'll fire when we get about here the r aable bearing 350 range 98 range [Music] 98 con combat in effective range for intermediate speed torpedoes [Music] range 88 KH combat one minute to attack Point KH Roger [Music] out KH combat we're close enough now for highs speeded Torpedoes range 80 range 75 range 65 range 60 o attack Point Captain coming left to 317 stand by to Fire comper Control combat

[Music] [Music] him there the fish [Music] all right let's finish her off ready fire Salvo they're on their way you can see the shells as they fly through [Music] space there's flag in range we're over down to O ready fire [Music] Salvo all guns Salvo fire interval 4 seconds scratch one enemy Cruiser we have met the enemy and they are ours our radar found them through the darkness told us their course their speed their disposition radar guided our Torpedoes aimed our guns radar cost us hundreds of millions and it was worth it our technical equipment is the best in the world war bonds paid for it but it will cost us Millions more to maintain that superiority Millions for further research Millions for further development the future security of our nation depends upon such developments and they are all expensive those Millions must come from victory bonds buy bonds and hold them it's early morning at a b29 base in the [Music] Marianas the big bombers are getting ready for a mission and the men are getting ready in the essentials The Briefing differs little from others there's a Target that'll be bombed they will proceed to this point in space above the Earth drop their bombs and return without ever seeing the target these are the instructions the men are ready for the [Music] [Music] takeoff 6 hours a loft the huge Armada of super fors has spand over a thousand miles of trackless waters the weather Bears out the forecast clouds heavy overcast all the way to the Target at 23,000 ft they're above [Music] it below and be on lies the Japanese Mainland and somewhere beyond that the Target if the enemy took comfort in the thought that the Bombadier sees nothing more than this they were living in a Fool's Paradise for at a calculated instant tons of high explosives and yes even the atomic bomb would be sent away to the Target aimed by the miracle of radar before you know is the radar scope a small circular screen giving x-ray likee vision to the mysterious ious 11th member of the crew the radar operator until recently we've known little of what he does and even less about the instruments he uses basically radar equipment consists of a radio transmitter and receiver the transmitter sends a radio beam earthward if it strikes water the beam is not reflected the receiver picks up nothing and the scope appears dark as it is now over the Pacific Ocean but if the beam strike a solid object such as land it's reflected and shows light on the scope watch something's coming in now at the upper left adjusting the receiver control sharpens the picture there they are two islands both with mountains on them that should make them easy to identify according to the charts only two islands of this shape and Contour lie off the southern coast of honu the little one coima the other hachijojima two tiny dots on the face of the globe point the way for a cargo of [Music] Destruction 7 hours 10 minutes elapse time almost a full day's work for most but to the crews a mission less than half sweat it out the picture on the scope warns of Entry to the critical Zone the return shows a large land mass Japanese Coast over 100 miles of it you see that bright spot at the top of the peninsula not exactly the picture in travel folders but that's beautiful fujiama M Fuji Nature's Wonder the tourist's Delight now a beacon inviting disaster a reference point for final calculations Bader this is radar operator over this is Bader here go ahead the wind is from 2 68° at 138 mph ground speed on the bomb Run 3 94 mph data taken from the electronic Wonder instruments is converted to Precision aiming pinpoint bombing 17° right radar operator this is Bombadier over go ahead Bombadier the S side set up we're ready to bomb the bomb run begins with a turn directly over fujiama when the bright spot that is Fuji touches the black line the instructions are pilot start one quarter needle with turn rolling out on a heading of 31° Roger Bader open Bombay doors after turn Roger the moment for decision has arrived the moment when the target must be single out from hundreds of other invisible targets Coastline with a large city a a peninsula jutting out in a bay the city Tokyo this is the general Target area Northwest of Tokyo lies the specific Target the Kushi aircraft Factory at Koo a flick of the switch isolates the target image and here it is one tiny Speck of light the focal point for hundreds of giant bombers for a th000 tons of bombs the correct 9° right rer ready on 70° ready [Music] Mark Mark at the split second before the bombs are released the radar operator sees this arms [Music] away and this is what the [ __ ] sees his cities his factories in Ruins a lot of you out there are probably asking well why show us this the war's over well we wanted to let you in on one of the big secrets of the war thought you might be interested yes you're right the war is over and we won it and by we I mean the foot soldiers the men at Sea the crews who flew the missions you men and women who worked in the factories the scientists who gave us radar and the atomic bomb and every last man woman and child who bought war bonds that was all part of winning the war but now there's a matter of the peace most of the men in uniform will be returned to civilian life likewise Factory workers will go back to producing civilian Goods but our scientists must go on perfecting old inventions and developing new ones for the security of our nation at peace and you who bought Bonds in support of the war effort can buy a share in the Peace by investing in bonds today how about [Music] it [Music]
