Stainless steel hulls, should be a step beyond whatever primitive ones are made of.

I have to admit, I have no concept what titanium steel is supposed to be.

To be fair, if you have a fusion power plant you can pretty much use anything convenient as reaction mass. Maybe the waste helium? It's got to be disposed of somewhere. Theoretically, you're turning tons of liquid hydrogen into it on a weekly basis...

The reaction drive can be a fusion rocket without the fusion power plant yet being invented, the power plant is still fifty years away,,,

the reaction drive does not require a power plant, oddly you can't tap it to generate electricity...

Except reaction drives show up at TL 7 and fusion power plants aren't till TL 8. You could say though that it is a fusion drive but it doesn't produce any excess power. Not sure anyone would want to launch such a ship from anywhere they liked though.

A fusion torch is pretty much the only description that makes any "real world" sense...
which means Earth based starports are likely in the middle of nowhere and number of launches limited - that or stick with chemical rockets to get stuff to Earth orbit.

Fusion torch from the Moon, Mars etc, from space stations a chemical rocket tug getting you to a safe distance from the space stations...

"Titanium steel alloy refers to alloys that combine titanium with steel or other elements, enhancing their properties.

• Properties: Titanium alloys are known for their high tensile strength, lightweight, and extraordinary corrosion resistance.

• Applications: These alloys are commonly used in aerospace applications, such as jet engines and spacecraft, due to their strength and lightweight nature.

• Comparison with Steel: While steel generally offers higher tensile strength, titanium's strength-to-weight ratio is superior, making it advantageous in many applications. "

That would be Robinson Crusoe on Mars 1964.
