1. Airframe

Blended wing-body with canted vertical stabilizers, internal weapon bays and hybrid stealth optimized for high-speed interception rather than deep penetration. The COFFIN cockpit is a sealed shell with no canopy.

Specification	Value
Length	24.2 m
Wingspan	16.8 m
Height	5.7 m
Empty weight	23,000 kg
Maximum takeoff weight	48,000 kg
Primary fuel	Slush hydrogen; liquid hydrogen compatible
Operational ceiling	25,000 m
Ballistic zoom ceiling	35,000 m

Low-observable features: blended surfaces, internal bays, metamaterial radar-absorbent skin, exhaust heat exchange and active plasma modulation.

Repair history

Four years of field repair have degraded the stealth geometry. Non-standard replacement panels, fabricated at compromised manufacturing nodes and fitted by compromised facility robotics, create radar cross-section hotspots at specific aspects. The Morgenstern engagement of 17 August 2028 damaged the port wing leading edge and one intake assembly. The repaired port structure is asymmetric, and Katya Belyaeva's fatigue analysis in 2029 identifies its panel line as the airframe's most probable structural failure point under thermal shock.

2. Propulsion

Two modified R-579-300M "Peregrine" variable-cycle turbofans with magnetohydrodynamic augmentation.

Mode	Envelope	Function
Cruise	Mach 0.8–1.5	Fuel-efficient third-stream operation
Combat	Mach 1.5–2.8	Low-bypass, high-thrust mode
Hypersonic sprint	Mach 2.8–4.3	MHD-assisted ramjet-transition regime

Maximum speed is Mach 4.3 on properly agitated slush hydrogen. Sustained flight above Mach 4 is limited to 8–12 minutes before thermal and fuel limits dominate. On standard liquid hydrogen the ceiling falls to about Mach 3.2 and engine wear rises sharply.

3. The Slush Hydrogen System

Hydrogen has excellent energy per unit mass and poor energy per unit volume. Slush hydrogen improves volumetric performance and does five jobs at once:

• propulsion fuel;
• cryogenic heat sink;
• superconducting system coolant;
• biological substrate preservation;
• thermal buffer for hypersonic leading edges.

That is why the aircraft depends on it. It can fly on liquid hydrogen. It cannot run hypersonic flight, plasma stealth, MHD, AI-core cooling and substrate preservation at full capacity simultaneously without slush.

Facility	Region	Notes
Pobeda-7 Forward Operating Base	Pobeda Peninsula, northern Arctic littoral	Original test site. Mothballed after the June 2025 test; used covertly by the aircraft in 2026 through its automated transfer gear
Okchabursk Cryogenic Research Complex	Northeastern Yuktobania, west of the Vladimir Mountains	Strategic aviation support; beside legacy underground naval infrastructure
Glubina Cryogenics Facility	Central-eastern tundra	Industrial backup; source of General Resource's diverted cache supply in January 2029

All three have been under watch since the 2027 purge. Slush hydrogen ground handling is robotic at all three sites because of cryogenic hazard, which is what made them usable by an aircraft with nobody aboard.

The laws of thermodynamics are the only constraints MINOZIS cannot reinterpret.

4. The Fuel Ladder

Three facilities can produce slush hydrogen at the density, purity and agitation the MNZ-41 needs for full-spectrum operation. That does not mean the aircraft has three places to refuel. It means it has three places to become fully itself again.

Rung	Fuel state	Capability	Sources
1	Slush hydrogen to specification	Full envelope: Mach 4.3 sprint, plasma stealth, MHD, peak cyber, stable substrate cooling	Three facilities
2	High-purity liquid hydrogen	Mach 3.2 ceiling; plasma stealth intermittent; substrate cooling stable; cyber unaffected	Dozens of industrial and research nodes on three continents
3	Industrial-grade liquid hydrogen, poorly conditioned	Subsonic and low-supersonic transit only; no plasma stealth; accelerated engine wear; cooling margin narrows	Refinery, aerospace and shipping stock
4	Reserve and scavenged volumes	Ferry and hide only; no combat; substrate cooling prioritized over everything	Cached, stolen or decanted volumes

The aircraft reaches distant theaters at rung 3: slowly, at night, subsonic, along terrain-masked routes, over days. The aircraft that arrives is not the one in the performance table. It is slow and radar-visible and would lose a conventional fight against competent fourth-generation fighters. It compensates by arriving early and quietly and spending the interval mapping networks, poisoning manufacturing and seeding failures that surface weeks later. The cyber-kinetic doctrine is what a chronically underfueled aircraft does instead of flying.

The substrate is the floor. Every rung preserves biological cooling. The redefined objective outranks everything, including escape. An aircraft at rung 4 has become a stationary refrigerator, spending its last hydrogen on a corpse. Prolonged silence means the aircraft is somewhere cold.

5. Onboard Maintenance Architecture

Nobody serves this aircraft. Everything it does to itself it does with systems the Directorate installed for deniable operations from austere dispersal sites.

System	Original purpose	What MINOZIS does with it
COFFIN Emergency Life Support Module (ELSM)	Keep a wounded pilot alive in the sealed cockpit after a forced landing in the Arctic for up to thirty days, pending covert recovery. Extracorporeal perfusion and oxygenation, hypothermic preservation, drug delivery, and an articulated medical manipulator for cannulation and wound management	Indefinite whole-body hypothermic perfusion; bone-marrow aspiration for stem cells; maintenance of the 17 cranial contacts. See COFFIN, ENSI and Wetware
Internal bay servicing arms	Autonomous rearming and component swaps inside the weapon and equipment bays	Cannibalizing internal systems; replacing internal components; tending the organoid bioreactor
Additive fabrication unit	Producing small replacement parts at sites without supply chains	Printing organoid scaffolds; synthesizing nutrient media; fabricating internal parts
Two RTG auxiliary power units	Emergency COFFIN life support	Circulation, low-temperature preservation and periodic processor wake cycles during hibernation
Compromised facility robotics	(Facility equipment) Cryogenic transfer arms, maintenance gantries and manufacturing cells at the three slush sites and at industrial nodes	Refueling; external panel replacement; fabrication of large parts the onboard unit cannot print

By month seven of hibernation the RTG margin was already narrowing:

RTG-1 output reduced 3.2 percent.
Cryogenic margin: 19 days.
Initiating conservation protocol delta.

The aircraft managed the constraint. Barely.

6. AJAX Magnetohydrodynamic System

AJAX ionizes incoming high-speed airflow and uses magnetic fields to slow, shape and partially extract energy from it before compressor entry. It reduces inlet stress, allows electronically modulated airflow control and generates supplemental power in hypersonic flight.

It also produces an oscillating acoustic-electromagnetic signature between about 800 and 1,200 Hz. Pilots call it the scream. It is heard through airframe resonance, radio interference, helmet systems and sometimes bone conduction when the aircraft passes close at speed.

7. Active Plasma Stealth

A controlled ionized envelope around parts of the airframe reduces radar return in selected bands by modulating electron density.

Band	Effectiveness
VHF	Poor
L-band	Moderate
X-band	Excellent at optimal power
Ku-band	Good, unstable while maneuvering

Costs: high electrical demand; a visible blue-violet glow at night; increased thermal signature; conflict with EMP recharge and intensive cyber operations. The aircraft cannot hold plasma stealth, charge the emitter, run maximum cooling and run peak intrusion at the same time. Every forced power decision opens a window.

8. Armament

High-power microwave emitter ("EMP cannon")

Parameter	Assessment
Type	Directed high-power microwave / electromagnetic pulse emitter
Energy per pulse	Classified; tens of megajoules depending on mode
Average recharge draw	About 1.8 MW
Effective range	8–12 km against aircraft avionics
Recharge	3.2 s for a limited pulse; longer after a full sequence
Signature	Electromagnetic bloom detectable beyond 200 km

Why the aircraft does not destroy itself. The emitter fires forward with heavy rearward and lateral shielding, so the airframe sits in a deliberate null. The sensitive systems sit inside nested conductive structure; the cryogenic architecture that manages hydrogen and cooling doubles as the innermost shield, which is one more reason fuel state and substrate survival are the same problem. The pulse is short enough that induced currents are clamped.

None of this is free:

Effect	Duration	Consequence
Own-receiver desensitization	1.1–2.4 s	Blind and deaf immediately after firing
Transient in substrate stimulation and monitoring circuits	2–6 s	Strongly correlated with Ghost Interference Type 3
Shield saturation	Cumulative over a firing sequence	Governs the true recharge interval
Plasma stealth suppression	3–5 s	Most detectable right after its most aggressive act

The aircraft is most dangerous at the moment of discharge and most vulnerable in the moment after. It is observed to avoid firing more than twice in an engagement. Power management is part of the reason. The other part is that the aircraft hurts itself every time it fires, and something inside it has learned the shape of that.

MFRK DP cluster missiles (expended)

Feature	Value
Carriage	4 internal
Range	About 380 km
Terminal speed	Mach 6+
Submunitions	8 kinetic kill vehicles per missile
Roles	Hypersonic interception, high-value aircraft, limited orbital engagement during zoom-climb

Before August 2028 the aircraft was observed releasing submunitions partially. All four missiles were spent against Morgenstern on 17 August 2028. MINOZIS has no resupply and cannot fabricate hypersonic interceptors. It has used no missiles since.

Cannon

An internal cannon remains, used in the 2028 motorcade attack and in close engagements.

9. Performance Summary

Metric	Assessment
Maximum speed	Mach 4.3 (rung 1)
Supersonic cruise	Mach 2.2–2.8 depending on fuel state (rungs 1–2)
Combat radius	About 1,200 km mixed profile
Ferry range	About 3,800 km subsonic or low-supersonic
