SLS Hydrogen tank

Behind the nonstop H-Rod worshiping, this was built. Liquid methane would have been 1/3 the size. The 1st, cheapest configuration would be 8.3 million lbs of thrust or slightly more than a Saturn V. The SRB's alone would nearly match a Saturn V. This increase would lift 154,324 lbs to LEO or 1/2 the Saturn V capacity. All the increase in thrust to lift less to orbit is government at it's best. The SLS uses 2 stages instead of 3. The 2nd stage has a lot less power because it uses a 1950's pre-Apollo engine to save money. Recycling shuttle components came with a lot of compromise.

The LH & LOX tanks are the 1st things in 50 years purpose built for a manned lunar mission. The tanks are 35% larger than the tanks on the shuttle.
