TriSeadon Crew Assignments

USN and USMC shipboard crews, billets, departments, and embarked team breakdowns by class.

Crew Assignments

This page is about ship crews and military billets, not industrial workforce. It breaks each class down from top-line crew size into ship's company, embarked aviation, medical, mission-detachment loads, and maximum berthed capacity. The further down you open the page, the more specific the breakdown gets.

Category rule: crew assignments here mean USN and USMC personnel carried on or assigned to the ships. Workforce and manpower for building, refitting, and sustaining the fleet belong under the shipyard, training, and logistics side of the program.

Planning rule: TriSeadon uses automation to cut wasted labor, not to run ships with hollow watchbills. These complements are intentionally heavier than Zumwalt-style austerity so the fleet can maintain systems properly, stand full watches, and absorb combat or deployment fatigue.

Crew Logic

Full fighting complement: ship's company plus normal embarked aviation, medical, and mission packages required for that class to fight as designed.
Maximum berthed capacity: the number of people the hull can house when surge detachments, staff, VIP support, trainees, or crisis-response loads are embarked.
Not workforce: these numbers do not describe shipyard workers, depot maintainers, or industrial-base labor.
Core watchstanding rule: enough people to man Bridge, CIC, Engineering, ATC, DMC, damage control, security, maintenance, and flight operations without cannibalizing the next watch section.
Seniority rule: more senior watch leaders than thin-manned modern ships, but still more junior enlisted than old manpower-heavy fleets because automation removes some routine labor.
Berthing hierarchy: enlisted ATLAS outfits scale by department mix; E7-E9 use shared four-to-six-person CPO compartments except for the private Command Master Chief cabin; officers normally share two-person staterooms except for private CO, XO, and Chief Medical Officer cabins. The CAG also provides private cabins for its Lead Flight Officer and senior USMC QRF officer. Open the layouts.

Ship-Service Ownership

TriSeadon retains the proven central-service model rather than putting laundry or retail functions inside berthing neighborhoods. One central ship-service zone contains the laundry, barber shop, and ship's store. Current Navy ownership is divided among Retail Services Specialists (RS) for laundry, barber, and retail operations; Logistics Specialists (LS) for supply and inventory; and Culinary Specialists (CS) for the fixed galley and mess facilities. Damage-control lockers remain fixed, distributed, and staffed through the ship's damage-control organization.

CAG Crew Breakdown

Full fighting complement: 450-500.

Maximum berthed capacity: 580.

CAG | Top-Level Breakdown
  • Command, flag, CIC, ATC, and DMC: 34-40.
  • Engineering and electrical: 108-118.
  • Deck, weapons, damage control, and security: 78-88.
  • Operations, sensors, sonar, EW, and communications: 82-92.
  • Supply, admin, and food service: 28-34.
  • Medical detachment: 18-20.
  • Aviation detachment: 60-78.
  • QRF Marines: 32.
  • Precision support: 2-4.
  • Surge, flag, VIP, and guest capacity: remaining margin up to 580 supports extra mission staff, visiting command teams, security details, trainees, diplomatic support, and crisis-response surge berthing.
CAG | Rank Structure Overview
  • Officers: about 38-48 across command, engineering, air, medical, operations, and flag functions.
  • Chiefs and senior enlisted: about 52-64 across watch leadership, maintenance leadership, division LCPO roles, and detachment senior billets.
  • Junior enlisted and NCO operators: about 360-388, including QRF Marines and most maintainers, watchstanders, deck ratings, and ship-service personnel.
CAG | Department Drill-Down
Command, Flag, CIC, ATC, and DMC | 34-40
  • Typical officer spread: CO, XO, department heads, OOD-qualified bridge officers, CIC leadership, air-control officers, and DMC supervisory officers.
  • Typical senior enlisted spread: command master chief, senior watch supervisors, ATC watch leads, DMC leads, CIC chiefs, and quartermaster/OS leadership.
  • Typical rates: `OS`, `QM`, `IT`, `ET`, `CTT`, `CTR`, `IS`, and cross-qualified drone-control watchstanders.
  • Flag and state-use spaces: this section also supports embarked admiral staff, ready room, briefing room, dedicated flag quarters, and a VIP-standard suite suitable for national-command or allied-leader visits when required.
Engineering and Electrical | 108-118
  • Purpose: man tri-power plant, AEGIR distribution, switchboards, auxiliaries, damage isolation, chilled water, pumps, and refit-ready equipment spaces.
  • Typical seniority: deeper chief coverage than Zumwalt-style manning because the plant still needs real maintenance and casualty-control depth.
  • Typical rates: `EMN/EM`, `GSM`, `GSE`, `MM`, `MR`, `DC`, `HT`, and related electrical/control technicians.
Deck, Weapons, Damage Control, and Security | 78-88
  • Purpose: seamanship, line handling, anchor detail, magazines, gun crews, Cerberus support, topside security, VBSS support, and repair-locker staffing.
  • Typical rates: `BM`, `GM`, `FC`, `MN` where assigned, `MA`, and `DC` support watchstanders.
  • Watch logic: enough people to keep topside defense, small-boat support, security watches, and repair lockers manned while flight or combat ops continue.
Operations, Sensors, Sonar, EW, and Communications | 82-92
  • Purpose: SPY-6, fire-control radar, sonar, EW, CEC/CANES/JADC2, crypto, UAV-control integration, and battle management.
  • Typical rates: `OS`, `STG`, `ET`, `FC`, `IT`, `CTT`, `CTR`, `IS`, and drone or sensor-fusion operators.
  • Manning logic: this section is heavier than modern thin-watch crews because TriSeadon treats DMC, EW, ASW, and aviation-control as real sustained warfare spaces.
Supply, Admin, and Food Service | 28-34
  • Purpose: supply, central laundry and retail services, food service, pay/admin, logistics records, issue control, and sustained sortie support.
  • Typical rates: `LS`, `RS`, `YN`, `PS`, `CS`, and related support ratings.
Medical | 18-20
  • Officer mix: 1 medical department head, 2 ER surgeons, 1 anesthesia or critical-care officer, 1 dental officer.
  • Senior enlisted: 1 E-7 IDC/LPO and 1 E-6 senior HM.
  • Enlisted medical staff: 12-14 `HM` in the E-3 to E-5 range, covering trauma room, recovery, imaging, records, lab, and patient support.
Aviation | 60-78
  • Aircraft: 2 UH-1Y, 2 AH-1Z, and 3 mission-configured MH-60R/S helicopters, plus MQ-19 Aerosonde, MQ-27 ScanEagle, RQ-21 Blackjack-compatible, and other mission-selected UAV packages.
  • Pilots: 8 USMC pilots for the Marine aircraft and 6 USN pilots for the MH-60s.
  • Crew chiefs: at least 7 at E-5 to E-7.
  • Maintenance officers: 1 USMC and 1 USN minimum.
  • Typical rates and MOS mix: `AD`, `AE`, `AM`, `AT`, `PR`, `AS`, `AO`, fuels support, plus Marine aviation maintenance MOS billets.

DDG | Department Drill-Down
Command, CIC, ATC, and DMC | 22-28
