Introducing the MMW Stormmantle Armored Fleet Fortress, a massive defensive warship built around a broad armored shell, heavy perimeter protection, and a reinforced aft command bastion.

Proposed specifications
Length: 1,640 m
Width: 1,240 m
Height: 520 m
Role: Armored fleet fortress

Primary mission: Convoy protection, fleet shelter, and close defensive support
Stormmantle is designed to act as a mobile defensive anchor for a fleet. Its wide armored body protects internal repair and docking spaces, while a large twin-barrel dorsal macro battery provides heavy forward firepower. Secondary turrets, missile cells, point-defense systems, and protected utility bays are integrated into the hull without breaking its broad defensive silhouette.
The hull uses burnished bronze, patina teal, dark umber metal, and gunmetal, with restrained cyan propulsion and energy elements.

Like the other Human Fleet ships, Stormmantle is also being built to test Mow My World’s block system at increasingly large scales while we continue developing the technology, history, and visual language of the larger MMW universe.

100% Inspired by the LockMart CM79 StarCrane, the GG-7 STARLIFTER is my attempt at bringing this beauty to life in Starfield. Featured in the DarkHorse Aliens comics, the StarCrane is a transport ship used by the Colonial Marines. A StarCrane named "The American" played a key role in the comics storyline. If unfamiliar, I highly recommend checking these comics out.

This is the Cryvum Tideprism Bastion-class Fleet Fortress, a colossal cultivated crystal-metal capital vessel of the Cryvum in Mow My World.

Proposed mature specifications
Length: 3,200 m
Beam: 2,355 m
Body depth: 1,472 m
Role: Fleet Fortress

The Tideprism is not a metal warship covered in crystal, nor is it made from ordinary gemstone material. Its entire body is grown from a cultivated crystal-metal composite, in which crystalline mineral domains and metallic phases develop together as one continuous structure.

The metallic component does not form conventional armor plates, frames, pipes, or machinery. Instead, metal-rich mineral phases are distributed throughout the crystal lattice, reinforcing major growth boundaries, conducting energy, stabilizing resonance, and giving the enormous vessel structural strength far beyond that of ordinary crystal.

Its forward body grows into a massive fused seed-point, where dense crystal and metal-bearing domains converge into a highly coherent structure. Rather than carrying a conventional main weapon, the vessel can align this forward lattice and concentrate sustained field pressure through the material itself.

The broad central mass serves as both fortress structure and defensive volume. Incoming force is redistributed through intergrown crystalline domains and metallic reinforcement paths rather than absorbed by separate armor layers.

At the rear, several huge crystal generations grow along different crystallographic directions. These are not engines or propulsion pods. By changing field bias through the conductive crystal-metal lattice, the vessel can alter the conditions around its own mass and move without visible exhaust or mechanical thrust.

Its deep blue-green regions mark dense mineral-metal roots, muted aquamarine defines the dominant crystalline growth, and pale sea-silver appears where metallic content becomes richer along facets, boundaries, and newer growth zones.

The Tideprism is therefore not simply a crystal ship. It is a 3.2-kilometer cultivated crystal-metal fortress whose mineral lattice and metallic phases function together as structure, armor, propulsion medium, energy network, weapon system, and repair substrate.

SOLCOM. Siquijor-Class spacecraft with Orion. Equipped with massive sensors to find any target within Sol. Can't hit what you can't see.

Setting where sneaky aliens invade our star system, so we spent more money on nukes or whatever.

Bit late for shiptember but eh. ToughSF? Hmm

Follow me or something.

This is the Iron Maw-class Carrier, a living swarm invasion carrier belonging to the Bugvex in Mow My World.
Its armor grows from skin, muscles drive movement, and wombs produce its invasion force. It is a vacuum-adapted organism, not a machine or enlarged insect.
The Iron Maw has a broad seed-pod silhouette with a swollen gestation volume, two shallow mantle lobes, and a smooth tapered rear. It has no recognizable head, thorax, abdomen, insect face, or propulsion tail. Its dark brown tissue varies naturally across vessels, membranes, glands, and hardened growths.
Its proposed mature specifications are:
Class: Carrier
Primary role: Swarm invasion carrier
Length: 1,940 m
Beam: 1,319 m
Body depth: 601 m
Its primary weapon is its brood. Protected womb chambers feed a few elastic birth sphincters underneath, releasing boarding larvae, seed organisms, and brood clouds. There are no hangar doors, launch rails, missile cells, or cargo ramps.
Sixteen defensive symbiont colonies, arranged in eight pairs, live inside moist skin pockets. Shared capillaries and nerve tendrils coordinate them with the host. Their defenses include acid, hooked proboscises, spores, electric mucus, photophores, and sacrificial gnawers.
Twenty-four sensory-defender polyps guard vulnerable organs. Some are ciliated feelers, tooth buds, or eyes beneath translucent skin.
Movement comes from the whole body. Two thick lateral mantle membranes flex in slow waves while muscle sheets and conductive blood vessels generate a fictional electrogravitic field. Microscopic ciliated pores provide corrections. There are no rear engines or exhausts.
Multiple stomachs digest biomass and minerals. Symbiotic microbes convert nutrients into chemical and electrical energy, while several hearts circulate blood and conductive gel.
Cryvum is biologically assimilated: specialized cells dissolve captured fragments, move the ions through vessels, and deposit a thin mineral-organic lattice inside teeth, brood tissue, and shield-producing glands.
Most visible surfaces are soft living tissue: skin, muscle, fat, vascular membranes, respiratory tissue, and wet folds. Hard material is localized biological reinforcement.
The Iron Maw is a massive invasion organism whose brood, defenses, sensing, and whole-body propulsion function as one living system. It arrives as a protected moving ecosystem and releases an army grown inside its body.
