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.

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...

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.
https://www.bing.com/ck/a?!&&p=60ec...GVkaWEub3JnL3dpa2kvVGl0YW5pdW1fYWxsb3lz&ntb=1 - Applications: These alloys are commonly used in aerospace applications, such as jet engines and spacecraft, due to their strength and lightweight nature.
https://www.bing.com/ck/a?!&&p=3f97...udGVjaHN0ZWVsLm5ldC9hbGxveS90aXRhbml1bQ&ntb=1 - Comparison with Steel: While steel generally offers higher tensile strength, titanium's strength-to-weight ratio is superior, making it advantageous in many applications. "

Titanium is used in submarine construction, primarily due to its high strength-to-weight ratio, corrosion resistance, and non-magnetic properties.
These characteristics make it ideal for deep-sea diving and stealth operations.
Why titanium is used in submarines:
High Strength-to-Weight Ratio:
Titanium alloys are stronger than steel but weigh significantly less, allowing for lighter submarine hulls and increased diving depth.
Corrosion Resistance:
Titanium's resistance to corrosion in seawater is crucial for the long-term durability of submarines.
Non-Magnetic Properties:
Titanium is non-magnetic, making submarines less susceptible to detection by magnetic anomaly detectors (MAD) used in anti-submarine warfare.
Deep Diving Capabilities:
Titanium's strength and ability to withstand pressure make it suitable for submarines designed to operate at greater depths.
Examples of titanium in submarine construction:
Soviet/Russian Submarines:
The Soviet Union and Russia have utilized titanium in submarines like the Alfa, Sierra, and Mike classes, including the K-278 Komsomolets.
Hulls and Components:
Titanium is used in submarine hulls, propellers, and various other components.
Considerations:
Cost:
Titanium is significantly more expensive than steel, which has historically limited its widespread use in submarine construction, particularly in Western navies.
Fabrication:
Titanium is more challenging to weld and shape than steel, requiring specialized expertise and careful handling during construction.
US Navy:
While the US Navy has experimented with titanium, it has primarily used steel for submarine hulls due to cost and manufacturing challenges.

The SR-71 Blackbird used a high percentage of titanium in its construction because it was the only metal that could withstand the extreme temperatures generated by flying at Mach 3 speeds, while also remaining relatively lightweight. Approximately 85% of the aircraft's structure was made of titanium, with the remainder consisting of composite materials and some stainless steel.
Here's a more detailed explanation:
High-Temperature Resistance:
Titanium alloys were chosen for their ability to withstand the intense heat generated by friction with the air at speeds exceeding Mach 3.
Lightweight:
While strong, titanium is also relatively lightweight compared to other metals like steel, which was crucial for achieving the Blackbird's high speed and performance.
Specific Alloy Choice:
Lockheed used a titanium alloy that was more easily worked, though it softened at lower temperatures. This required them to develop new fabrication methods for working with the material, which have since been applied to other aircraft.
Expansion Challenges:
Titanium expands when heated, and the Blackbird was designed with this in mind, with parts fitting loosely when cold and snuggly when heated to operating temperature.
Manufacturing Challenges:
Working with titanium was not without its challenges. Lockheed had to develop new techniques for cleaning and machining the metal, including using distilled water to prevent corrosion from tap water and avoiding cadmium-plated tools.
Soviet Supply Chain:
Due to limited domestic supplies, the US sourced some of the titanium for the Blackbird from the Soviet Union through third-party countries and intermediaries.

It would come down to exactly what the proportions are.
And from what I knew of submarine and aerospace construction, rather disproportionate.

The V-2 missile, also known as the Aggregat-4 (A-4), was a long-range ballistic missile developed by Germany during World War II. It was the first practical example of a guided missile and was a key milestone in the development of space technology. Its construction involved a complex structure
of sheet steel, a wooden framework in some sections, and various specialized components.
Key Components and Construction:
Structure:
The main body was constructed from thin sheet steel, welded and riveted, with a wooden framework in certain areas.
Warhead:
The nose cone housed a warhead containing 1,650 lbs of amatol explosive, detonated by an impact fuse.
Guidance and Control:
An instrument section behind the warhead contained the guidance and control systems, including gyroscopes and electrical relays connected to graphite vanes in the thrust chamber.
Propellant Tanks:
The center section contained two large tanks, the upper one holding alcohol and water, and the lower one holding liquid oxygen (LOX).
Engine:
The tail section housed the rocket motor, a turbopump, a steam generator, and associated plumbing.
Cooling System:
The motor employed regenerative and film cooling to manage the extreme temperatures generated during combustion.
Fuel:
The rocket was fueled by alcohol and liquid oxygen.
Construction Process:
Early Development:
The initial development of the V-2 took place at the Peenemünde Army Research Center, with the first trial runs conducted in mid-1943.
Mass Production:
After the bombing of Peenemünde, production was moved to the Mittelwerk underground factory in the Harz mountains, where slave labor was used to construct the missiles.
Complex Launch Procedures:
Launching a V-2 was a complex operation, requiring specialized equipment, a large team of soldiers, and a flat, firm launch site.
Guidance System:
The guidance system relied on gyroscopes and graphite vanes in the thrust chamber to control the rocket's trajectory during the initial launch phase.
Significance:
Spaceflight Legacy:
The V-2's technology, particularly its guidance and rocket engine design, played a significant role in the development of later space rockets, including the Saturn V.
Mass Destruction:
Despite its contribution to space exploration, the V-2 was also a weapon of mass destruction, used by Germany to target civilian populations during the war.
The V-2 missile was a remarkable feat of engineering for its time, demonstrating the potential of rocket technology while also highlighting the destructive power that such technology could unleash.
