Overview
Greenband Pursuit Destroyer is a compact sea-surface warship designed to pursue and engage heavily protected targets. Its narrow hull, armored forward shoulders and concentrated bow weapons give it a clear attack direction, while low sensing ridges and a powerful stern drive support the pursuit.
It is grown as a continuous crystal-metal body. The waterline, buoyant lower hull and coherent bow-to-stern structure make it an ocean vessel in its own right, rather than a spacecraft adapted by placing it on water.
Vessel Profile
Dimensions & Scale
Length 24.4 m × Width 3.9 m × Height 2.3 m. Total height combines the supplied 1.2 m above the design waterline and 1.1 m draft. The hull operates at this waterline by displacement. These are fictional concept dimensions.
Proposed surface displacement: approximately 59 ton (metric tons). Fictional estimate using the stated draft and an assumed immersed-volume coefficient; not measured performance.
Weapons & Armament
Two concentrated forward emitters form the primary anti-heavy battery. Medium flank attack apertures, compact launch cells and smaller defensive outlets extend protection around the main firing axis.
Each weapon grows from the same material as the hull. Rooted projector spines, recessed firing wedges and split-prism launch cells replace separate mechanical mounts. The largest active apertures carry the strongest pale internal light; secondary and defensive openings remain smaller and more restrained.
The primary battery is brought to bear along a stable forward pursuit line. Flank apertures pressure targets crossing that line, while defensive outlets cover the withdrawal. The compact launch cells carry a limited reserve of crystal shards; firing, steering and interception draw on the same cultivated energy paths.
External Anatomy
Above the waterline, thick protective shoulders, low combat terraces and sensing ridges form the fighting body. A continuous dark, metal-rich crystal belt reinforces the waterline. Below it, a smoother buoyant belly and restrained longitudinal ridges maintain a coherent displacement hull.
Two heavy bow growths flank a lower wave-splitting keel ridge. The prow carries frontal combat loads while parting the water; a modest bow wave and clean wake express the vessel’s movement through the sea.
Fused mineral domains carry localized malachite-like banding through major armor shoulders, the prow, dorsal terraces and stern. Deep forest-gray roots transition into dark mineral green and sage-silver faces, with a faint mint light inside functional outlets.
Metal-rich phases follow deep roots, structural load paths and the waterline belt. Crystal-rich phases organize sensing, weapon focusing, launch geometry and propulsion. Broad opaque faces and substantial material thickness define the ship’s appearance.
Functional Architecture
Low integrated sensing ridges support directional pursuit through optical facets, field-sensitive domains and fine resonance slits. The sensors coordinate forward emitter alignment, lateral threat tracking and stern flow control.
Deep connected roots distribute stored field energy between weapons, defenses and propulsion. Metal-rich growth reinforces the waterline, load paths and outlet rims. Clearer crystal domains focus sensing and attack. Damaged sectors can be isolated from the working lattice, but repair requires compatible mineral feed and time to regrow coherent roots.
Technical Specifications
Offensive rating: 68/100 — Paired forward emitters concentrate anti-heavy fire along the pursuit line
Defensive rating: 42/100 — Forward shoulders and a reinforced waterline protect a compact hull with limited broadside depth
Mobility rating: 86/100 — A narrow displacement body and strong hydrolattice stern favor interception and rapid lane changes
Tactical cognition rating: 78/100 — Directional sensing ridges maintain contact and coordinate fire with supporting units
Endurance rating: 40/100 — Small energy and launch reserves constrain extended pursuit and repeated heavy discharge
Fleet support rating: 34/100 — Target-track relay and screening support a formation without large servicing capacity
Fleet Role
A compact anti-heavy pursuit destroyer for screening ocean approaches, intercepting armored raiders and sustaining contact until heavier formations can engage. Its task is to establish favorable firing geometry against a protected target, then disengage before a prolonged exchange consumes its reserves. It can patrol ahead of larger surface units and relay target tracks to supporting vessels.
Maritime Operations
One or two low sensing ridges integrate fine facets and disciplined sensor slits into the upper hull. The high-gain pursuit array emphasizes directional tracking without a tall mast or separate bridge tower.
At the stern, two to four large recessed hydrolattice channels and smaller steering channels accelerate seawater directly through the proposed Cryvum field system. Progressively oriented crystal faces define the aft drive region; there are no propellers or rocket exhausts.
Surface doctrine favors planned interception lanes, small steering corrections and a stable firing heading. The vessel retains immersion and trim as it changes speed. It operates as an ocean surface hunter; independent diving and space transit are outside this class’s assigned role.
Defense Architecture
Heavy forward shoulder domains and a reinforced prow protect the primary attack roots. A continuous dark waterline band carries stress around the buoyant belly, while smaller defensive outlets cover immediate threats at the flanks.
Survival doctrine depends on a clean pursuit lane, early threat recognition and retained stern capacity for withdrawal. The narrow vessel cannot spread heavy protection over every direction at once. Waterline damage is especially consequential because the buoyant body and its structural field paths share the same roots.
Operational Limits
The 24.4 m hull has limited space for launch reserves, growth feed and stored energy. Sustained firing reduces the field capacity available for steering and interception. Broadside exposure offers less protection than the reinforced forward sector.
Rough water and disturbed currents can interrupt the low sensor ridges and forward aiming line. A damaged waterline root affects trim as well as energy distribution. Major regrowth needs a support anchorage or a stable service interval; high pursuit mobility does not make every extended chase sustainable.
Strategic Strengths
A narrow hull, strong directional sensors and concentrated forward fire favor quick interception of a heavier surface opponent. Low integrated combat terraces retain a coherent sea-going body. Continuous crystal-metal roots let the vessel redistribute stored energy without a forest of exposed naval fittings. Its smaller operating footprint helps it patrol channels and reposition around larger ships.
Capability Assessment
Proposed fictional six-axis doctrine profile. Greenband prioritizes pursuit mobility and target tracking, with a concentrated forward anti-heavy attack. Compact reserves and limited broadside protection constrain endurance and support. The archive grade is C (58.0), reflecting a specialized small surface hunter rather than a general-purpose capital vessel.
C · 58.0
Fleet-wide concept rating, 0–100; not simulated performance. Specialized strengths do not imply an equally high overall grade. Tactical Cognition describes sensing, coordination and command. Grade is the equal-weight mean: S ≥ 90, A ≥ 75, B ≥ 60, C ≥ 45, D < 45.
Technology Level
Proposed T2 — integrated Cryvum crystal-metal field technology, coordinated sensing and material-state control. The tier follows the archive’s Cryvum vessel convention; this surface class is assigned to ocean operations.
Weapon Class
Proposed W1 — concentrated anti-heavy surface attack, compact shard launches and local interception. Tactical specialization does not assign capital-scale sustained fire.
T0 planetary · T1 system flight · T2 phase travel · T3 limited world engineering. W0 point defense · W1 ship combat · W2 heavy fleet combat · W3 strategic theater systems. Technology and weapon classes are independent of the profile grade.
History & Lineage
Universe lore · authored service history
Origin
Cultivated for ocean corridors where an armored hostile vessel can outlast lighter patrol craft but where a larger fleet cannot remain continuously on station. Greenband concentrates anti-heavy attack and pursuit sensing within a compact displacement hull.
Lineage & Branch
Cryvum surface-pursuit destroyer branch. Its malachite-derived banded growth is fused through deep structural roots, connecting the prow, waterline armor, combat terraces and directional stern. Greenband shares the ocean-hunter doctrine of Amberaxis while emphasizing a smaller hull and restrained mission reserves.

Individual History
The Greenwater Track — In this authored service history, a Greenband patrol maintains contact with an armored intruder along a narrow ocean approach. Its sensing ridges pass heading changes to a supporting formation while the forward emitters remain ready. Rather than open a costly exchange at poor alignment, the destroyer preserves the field reserve needed to hold the track.
The Split Wake — A change in currents disrupts the direct pursuit line. Greenband turns across a surveyed side channel and reacquires the target from a stable heading. Its brief attack forces the intruder to alter course toward the supporting formation. The patrol then withdraws for mineral replenishment, having completed the interception without exhausting its compact launch banks.
