  R4M rocket - Biocrawler
The R4M rocket (Rakete 4 kg Minenkopf) was the first practical anti-aircraft rocket, developed by the Luftwaffe during World War II, and used operational for a very brief time just prior to the end of the war.
In the post-war period the R4M served as the pattern for a number of similar systems, used by almost all interceptor aircraft during the 1940's and 50's.
Their designs had started out with the 20 mm MG 151/20 cannons, but it was found that it took an average of 23 rounds from one of these guns in order to down a B-17 Flying Fortress, a number that was difficult to achieve.

 Me 262: Stormbirds at War - R4M Rocket
The 55mm R4M Orkan (Tornado) folding fin missile was a formidable weapon fitted to Me 262s late in the war.
The R4M was unguided and the pilot simply used the usual Revi gunsite for aiming.
When the rockets were fired from a range of 600 meters, they had the same ballistics as the Mk 108 cannons.

 Spartanburg SC | GoUpstate.com | Spartanburg Herald-Journal
The R4M rocket, nicknamed the Hurricane (German: Orkan) due to its distinctive smoke trail when fired, was the first practical anti-aircraft rocket.
Two warheads were available for the R4M, the common PB-3 with a 0.4 kg charge for anti-aircraft use and the larger shaped charge, similar in construction to the Panzerschreck, the Panzerblitz II (PB-2), for anti-tank use.
The Luftwaffe found the R4M missiles to have similar trajectory to the 30 mm MK 108 cannon in flight, therefore the standard Revi 16B was utilized effectively.

 [No title]
The Germans had developed such a successful weapon (the R4M), but before long it was noted that neither the Japanese nor the Germans had any heavy bombers, and the weapon was switched to air-to-ground use.
The 70mm rocket became very popular in the 1960s, when it was discovered that the weapon worked very well when launched from multiple (7 or 19 tube) launchers mounted on helicopters.
The 42-55 inch long rockets could be fired singly or in salvoes, and gave helicopter pilots some airborne artillery for supporting troops on the ground.

 [6.0] Unguided Rockets
The R4M was a fairly potent weapon that was used in some numbers at the end of the war for air-to-air combat.
Instead of mounting individual rockets individually on a stores pylon, unguided rockets were fitted to aircraft in "pods" that could be streamlined and could carry a large quantity of folding-fin rockets.
Although not highly accurate, particularly because a folding-fin rocket tends to "jink" after launch until the fins deploy and the rocket stabilizes, it is generally fired in salvos and can saturate a dispersed target with shattering effect.

The general assembly process went as follows: First, the center section of the rocket (the fuselage with its two huge alcohol and liquid oxygen tanks) was assembled.
Then the tail section of the rocket with its propulsion ring, rudder servos, and fins was attached to the motor.
Halls 23 and 24 are reported to have been used for assembly and temporary storage of the shells for the central part of the rocket, while Halls 25 and 26 held storage and inspection areas for rocket subsystems.

 R4M Rocket
Minenkopf) rockets were fired from wooden launch rails mounted underwing.
With a velocity similar to the Mk 108 cannon, they could be aimed exactly the same as the cannon.
The R4M also had the effect of breaking up the tight bomber formations making them easier targets for the fighters.

 Messerschmitt Me-262
Before the end of the war it was also armed with R4M unguided 50mm air-to-air rockets, which also proved very lethal against bomber formations, also from stand-off range.
The German advantage in jet and rocket technology, and in many other fields of military technology, in the beginning of World War 2, was not a coincidence.
In jet and rocket technology, the Germans kept the technological advantage until the end of the war, but the errors, human errors, greatly reduced the actual military benefit from it, as was in the case of the Messerschmitt Me-262.

 :: Far Shores: Nazi UFOs Two-Part Article
After a nearly vertical launch on the power of its bi-fuel rocket motor and four jettisonable solid-fuel rocket motors, the Natter was expected to reach an altitude of 35,800 ft. in one minute.
It was planned to launch the rocket planes as U.S. heavy bombers approached, guiding them automatically from the ground to within a mile of the enemy.
Simultaneously the rear fuselage, containing the valuable rocket motor, would break off and be parachuted to earth, where the motor could be used again in a new Natter.

 Chronology - Quarter 1 1945
As a weapon for the jet fighters, the 5 cm R4M powder rocket was used.
Each fighter had 48 of these rockets, each of which weighed 7 kg and could propel 500 g of explosive at 400 m/s to a range of 1200 to 1500 m.
At least 11 V-2 rockets were fired at the bridge across the Rhine at Remagen, which had been captured by American forces.

Its rocket engine used liquid oxygen and alcohol, pumped in the thrust chamber by specially developed turbopumps.
Its shape was that of a small aircraft, with a sustainer rocket engine in its body, and two boost engines, mounted above and below its fuselage.
The R4M was not used on a large scale, but after the war many airforces introduced folding-fin aircraft rockets (FFAR) based on the R4M.

 The Messerschmitt Me-262 Schwalbe / Sturmvogel
Hans A. Mauch had become head of rocket development at the RLM in April 1938, and quickly expanded his office's charter to emphasize turbojet development, working with an experimental department under Helmut Schelp in the RLM research branch.
A ground-attack version of the R4M rocket was also designed and might have helped turn the Me-262 into an effective "Jabo" aircraft, much like the RAF's rocket-firing Typhoons or "Rockoons", but it does not appear the Luftwaffe ever used the Me-262 in this way.
A single "Me-262C-1a" was built with a Walter booster rocket placed in the tail to improve climb for the interceptor role.
