HTNP Industries will be Manufacturing heavy rockets with an incredible payload capacity comparable to current existing models. Company will be using solid fuel instead of compressed liquid fuel to Power it's massive propulsion engine.
If we look at the current scenario Starship, once complete, will be “world’s most powerful launch vehicle,” according to SpaceX, with a cargo capacity of 100 metric tons (that’s over 220,000 lbs) to Earth orbit. With orbital refueling, it’ll also be able to take its freight — and passengers — to the Moon, Mars and beyond.
And if we look into history During project Aelita (1969-1972) the Soviets were developing a way to beat the Americans to Mars. They designed the UR-700m, a nuclear powered variant of the UR-700, to assemble the 1400 t (3,000,000 lb) MK-700 spacecraft in earth orbit in 2 launches. The rocket would have a payload capacity of 750 t (1,650,000 lb) and is the most capable rocket ever designed. It is often overlooked due too little information being know about the design. The only Universal Rocket to make it passed the design phase was the UR-500 while the N1 was selected to be the Soviets HLV for lunar and mars missions.
If HTNP Industries succeed in manufacturing their rocket, it will be capable enough to carry a payload of 255T says it's co-founders Saurav L. Chaudhari and Shantanu P. Gawande.
