As it is pretty evident that spaceships are a somewhat inseparable part of the experience in Starfield. But customizing them can be a bit complicated, here's a guide to help players get familiar with the process.
Developer Bethesda has decided to keep the engineering of ships in Starfield a bit on the realistic side. The aerodynamics etc. follow the rules of astronomical physics.
To build their perfect ship, players have to make sure they are familiar with the basic icons and terminologies. Most of the time the UI consists of shortened names for everything.
LAS: Ship’s ability to damage with lasers.
BAL: Ballistics.
MSL: Missile damage.
Hull: The ship’s health.
Shield: The ability of a ship to take damage until it starts affecting the Hull.
Reactor: Energy provided by the ship.
Cargo: The window of trading smuggled cargo in secret with the scanner.
Crew Capacity: Crew members can the ship hold?
Fuel: The threshold of a fleet’s fuel holding capacity, including the reserves.
Jump Range: The longest distance your vehicle can move in light years.
Mobility: How efficiently does the fleet perform in the hardest of combat with response to controls?
