This topic about the Me 262 C-3 with booster !
The main drawback of the first “Defender of the House” was the limited capacity of the tanks for the turbojet engine. As a result, the Me 262C-3 was equipped with a Walter R P-211/3 rocket engine suspended under the fuselage with fuel tanks on bomb racks directly in front of the engine. The rocket engine could be dropped by parachute after running out of fuel. Fuel entered the rocket engine through flexible pipelines, but a problem arose - the tanks were located slightly lower than the engine, which made it difficult to supply fuel to the combustion chamber. This problem was never resolved until the end of work on the “Defender of the House”.

Side note :
Won’t make a suggestion about it !
C-3 have same C-2B engines
2 × Jumo 004 turbojets + 1 × Walter rocket engine
4 × 30 mm MK 108 cannons in the nose.
Walter HWK 109-509S rocket engine :
Spoiler
With the success of Walter’s HWK 109-500 “Rocket Assisted Take-Off Packs”, or “Starthilfe”, for larger or heavily laden aircraft, it was almost inevitable that this technique should be used for providing the means of increasing the rate of climb for a conventional fighter.
The success of the Me.262 jet aircraft had led to the German high command investing most of their technical expertise in it as the primary air combat option. Being able to power a fully laden Me.262 from the smaller airfields and landing strips with which the Jagdgeschwader were being forced to contend, and to bring the Me.262s to combat height quickly, were attractive goals. The Walter rocket packs were a serious contender for this requirement.
The Starthilfern had only a limited duration and by the standards of the hot Walter motors, limited power output. The more sophisticated HWK 109-509 series offered greater endurance and greater power. The original Heimatschützer I development fitted the Walter motor within the fuselage of the Me.262. But as these rockets required a high degree of maintenance, and reduced the available space for standard fuel tankage, this proved to be an impractical solution. The Heimatschützer IV was a bolt-on rocket pack which could be serviced externally to the Me.262, fitted when required, and if not needed, not carried as an extra weight burden. In Spring of 1945, Walterwerke had produced a new design of their basic 109-509 series motor, calling it the “109-509.S2”
This Walter motor was a combination of parts from an HWK 109-509.A2 and an HWK 109-509.C with a compact arrangement. The weight of the unit was 140 kg, with thrust rated at 2000 kg.
Two 600 litre jettisonable T-Stoff tanks were slung externally on the bomb attachment points under the aircraft’s nose, with the hydrazine hydrate (C-Stoff) carried in the rearmost converted fuselage tank. Fuel from the forward tanks was carried back to the Walter motor by flexible hoses
