The Robot 310 (also known as Lufttorped 7, LT.7 ) is a Swedish pulsed rocket engine with a pulsating jet engine , developed by Saab AB in 1946. Created under the influence of the German Fau-1 , the wreckage of which was found in 1944 in Sweden. It was not accepted into service.

History
In 1944, Germany for the first time used a massively fundamentally new weapon - the Fau-1 unmanned aerial vehicles. Much cheaper than manned bombers [1] , missile planes could launch in huge numbers, expose enemy rear lines to constant terrorist bombing and force him to divert huge resources to air defense without risk for German pilots or the cost of irreplaceable resources. Although due to its low accuracy, the use of the V-1 was only relatively effective, nevertheless, the missiles clearly demonstrated their high potential.
As early as the beginning of 1943, two V-1 missiles launched with test targets over the Baltic Sea crashed in Sweden [2] . The Swedes carefully studied the design of German missiles, completing their detailed technical description. The latest technology at that time was extremely interesting for the Swedish military, who decided to make the most of this rare luck.
In 1944, Saab AB, on the initiative of the Swedish Air Force, began developing a project of its own design of a cruise missile based on the simplified and improved design of the V-1. [3]
Design
Designed for use with military aircraft at enemy targets from outside the air defense range, the Robot 310 had a significantly redesigned design compared to the V-1. The Swedes placed a pulsating jet engine along the axis of the apparatus, removing the slots of the air intakes to the sides in the middle of the fuselage. Thus, the Swedes managed to significantly reduce the height of the apparatus. A twin-engine bomber was supposed to be the launch platform (probably Saab 18 )
The length of the hull, taking into account the engine, was 4.73 m, the wingspan of the direct wings was 2.5 m. The weight of the projectile was only 265 kg (it is not known how much per warhead was). The speed of the rocket was supposed to be about 670 kilometers per hour, with a radius of action of about 17 kilometers.
Tests
The production of experimental rocket samples began in 1949. About 180 units were manufactured and tested, but the rocket never went into mass production. Its characteristics were already clearly inadequate, so that in the conditions of active use of fighter jets and anti-aircraft anti-aircraft guns using projectiles with radio fuses, to guarantee the defeat of the target or at least the possibility for the carrier to remain outside the radius of the air defense of the target.
Robot 311
In 1947, Saab began developing an enlarged version of a swept wing rocket. It was supposed to increase the speed of the projectile due to improved aerodynamics. Ten rocket samples were tested in 1951-1953, but the program was closed due to obsolescence of the structure and completely insufficient radius of action (due to over-weighting reduced to 7.5 km).
