Overview
Lamellar Broadwall-class Heavy Battleship is a Human armored warship for sea-surface and space operations. Four integrated main-gun bastions surround a low protected command citadel above one continuous displacement hull, with three stepped courses of overlapping metal armor forming its broad fortress profile.
Vessel Profile
Dimensions & Scale
Length 318 M × Width 64.4 M × Height 48.7 M. Height above design waterline: 36.7 M. Draft: 12 M. Total physical height: 48.7 M, including the ordinarily submerged hull.
Operating mass: approximately 146,100 ton (metric tons). 318 × 64.4 × 12 M draft envelope × 0.58 displacement-volume coefficient × 1.025 ton/m³ seawater density, rounded.
Weapons & Armament
Four triple-barrel 460 mm main turrets provide a twelve-gun heavy battery. Two mounts occupy forward stepped positions and two occupy aft positions; the inner mounts are raised to clear the outer roofs. Four twin 127 mm secondary turrets cover the midship flanks, and four compact close-defense units protect separate deck corners. The fit does not add missile banks or a separate carrier air wing. All calibers describe the fictional MMW armament.
External Anatomy
A broad blunt-wedge bow, deep continuous belly and thick lower belt support four substantial gun bastions. The protected command chamber occupies the highest central terrace, surrounded by shorter service shoulders. Three shallow overlapping armor courses use large rectangular modules, solid backing, close joints and restrained rivet rhythm. Emerald and burgundy armor contrast with dark machinery and controlled copper borders. The lower buoyant hull remains smooth beneath the stepped upper treatment.
Functional Architecture
Manufactured armor, gun cradles and command districts share a continuous load-bearing structure. Separate magazine, power and handling regions feed the main and secondary batteries. Compact sensing, narrow protected command glazing and recessed communications support fleet coordination. Two low exhaust casings and one compact sensor mast remain subordinate to the gun masses. Maintenance passages, drainage lanes and service roots stay clear of weapon movements.

Defensive rating: 83/100 — Stepped armor, a protected citadel and isolated magazines provide strong protection
Mobility rating: 38/100 — Heavy hull mass and marine draft favor deliberate movement despite integrated space drives
Tactical cognition rating: 62/100 — Compact sensing and protected communications coordinate battery sectors and fleet requests
Endurance rating: 72/100 — Protected reserves and supported handling sustain repeated firing with cooling intervals
Fleet support rating: 47/100 — Heavy batteries guard fleet approaches while maintenance and carried-craft support remain limited
Fleet Role
Heavy Battleship. Twelve heavy main guns, stepped firing positions and extensive manufactured armor favor sustained fleet combat and bombardment. Dual-environment machinery permits service at sea and movement with space formations. Supported main masses and a low command core keep the gun battery central to the vessel identity.
Life Between Stars
At sea, a continuous displacement hull, rounded bilges, uninterrupted keel and protected marine propulsors support surface operation. Rudders and enclosed water-flow systems remain physically connected to the stern. Beyond the atmosphere, two large armored vacuum-drive groups integrated into the stern shoulders propel the same connected warship. Marine and space modes use protected machinery and finite reserves; neither adds a detached propulsion assembly. Underwater-submarine operation and independent phase travel are not assigned.
Defense Architecture
A pronounced upper armor belt, protected central citadel and deep occupied gun foundations shelter critical regions. Four close-defense units cover separated approaches, while isolated magazines and service routes restrict the spread of damage. Plate overlaps reinforce the armor surface without creating openings through the buoyant hull. Defensive strength depends on surviving structure, reserve availability and coordinated coverage rather than a limitless shield.
Operational Limits
The heavy body favors deliberate maneuvering, and gun preparation, handling and heat rejection constrain sustained output. Main turrets need clear firing arcs, leaving local approach sectors to the smaller batteries and escorts. Marine drafts and transfer conditions limit shallow-water access. Space relocation consumes reserve and cannot be treated as uninterrupted bombardment. Maintenance routes and service clearances are not spare hangars or extra weapon positions.
Strategic Strengths
Twelve heavy main guns, stepped firing positions and extensive manufactured armor favor sustained fleet combat and bombardment. Dual-environment machinery permits service at sea and movement with space formations. Supported main masses and a low command core keep the gun battery central to the vessel identity.

Individual History
Lamellar Broadwall-class Heavy Battleship completed its first Celdren firing trial with the inner main turrets raised over the outer roofs and every maintenance passage left open for inspection. Captain Maera Doss wanted the armor yards to demonstrate both combat strength and service access before accepting the ship. Battery officer Eren Sahl focused on the twelve heavy guns. Chief engineer Vessa Renn focused on the deep buoyant hull and the stern machinery that would later carry the same body beyond the atmosphere. Their different inspections established the working partnership that shaped the ship's first deployments.
The Selnareth defense formation assigned Broadwall to a coastal approach whose shallow inner reaches could not safely accommodate its draft. Maera held the battleship farther outside while smaller units surveyed the transfer route. Eren arranged overlapping main-battery sectors rather than turning every turret toward the nearest visible threat. Vessa maintained reserve for a change of position and kept marine cooling available during preparations. The broad armored body could dominate a selected approach, but it could not solve the depth of the inner water merely by carrying more guns or thicker plating.
A request from Crownblade Cradle Carrier changed the planned surface rendezvous. The submerged carrier had recovered a damaged craft and lost power in one service district, delaying its return schedule. Broadwall could withdraw on time or hold the outer access while the remaining galleries completed their work. Maera accepted a limited extension and asked Eren to preserve a battery reserve for the final crossing. The crew prepared separate firing sectors, leaving the protected transfer route clear. Vessa kept the marine machinery ready for repositioning while Eren divided the remaining battery preparation between the outer approach and the final transfer interval.
The outer approach came under pressure before Crownblade completed the return. Broadwall used a controlled main-battery sequence against the confirmed threat sector, then repositioned rather than sustaining every available gun at maximum output. One secondary service route overheated and Vessa isolated it, reducing local coverage without disturbing the continuous hull boundary. The transfer corridor remained open long enough for the carrier's delayed support exchange. Crownblade reported the preserved recovery interval; Broadwall reported the battery expenditure and the isolated machinery. Together the accounts described a successful bounded rendezvous with work still required afterward.
At Celdren, the battleship received repairs before its first extended space assignment. Vessa insisted that the stern-drive inspection include the machinery regions used during sea service, because relocation would place new demands on a body already carrying a known thermal fault. Eren supported a reduced readiness schedule so replacement handling equipment could be tested under realistic battery preparation. The ship later joined an orbital formation through its integrated vacuum drives, carrying the same armored terraces and finite stores. Its departure did not erase the coastal expenditure or turn every marine service system into equipment suited for vacuum work.
Broadwall's crew now plans each deployment around the environment it will actually occupy. Marine access depends on draft and protected water approaches; space movement depends on reserve, heat rejection and verified arrival support. Maera has accepted a return assignment to the Selnareth coast, where Crownblade will again require a guarded service window. Eren is training a new inner-turret crew, and Vessa has reserved maintenance time between relocation and coastal readiness. The battleship remains a heavy fleet battery because its crews can coordinate those limits, not because the stepped armor allows it to ignore them.
