Starfield: Starter build (vanilla, character level 20, 260k budget, no starship design required)

I started a new playthrough for the DLC and wanted to create a good early game ship. The result might not be the prettiest ship, but it's functional and could be even endgame viable. It can be built at character level 20 and does not require the starship design skill, but as it's a C class ship piloting rank 4 is required. After discounts from commerce skill, UC citizenship and Kryx's Journal 01 the cost for this is slightly below 260k.
goals:
- vanilla build
- buildable at level 20
- no starship design required
- best available weapons & shield
- high power for weapons
- 100 mobility
- 4+ crew slots
- no ladders
- some cargo
- hab space for interior design
- budget = 260k
conditions:
- selling parts of the original Frontier is fine
- Vanguard joined (Vanguard ship parts unlocked)
- full commerce skill (20% discount)
- UC citizenship unlocked (5% discount at UC vendors)
- Kryx's Journal 01 looted during "Back to Vectera" (2% discount)
- SAL-6830 Engine unlocked via "All That Money Can Buy" (SAL-6830 unlocked)
