Major doctrinal and architectural update across the Fischer 26 family. Three-tier altitude stack (Fischer 26 at 300 m AGL, Fischer 26E at 500–700 m AGL, Fischer 26E-LE at 1000 m AGL stand-off) replaces the earlier two-tier model. Three-tier procurement structure (Chinese/Ukrainian-proven / Western commercial / MIL-qualified) documented across all price-dependent pages. Stand-off EW doctrine for Fischer 26E-LE documented as drone-scale analogue to fixed-wing stand-off strike (Rafale+SCALP, F-35+JASSM-ER). All changes synchronised across English, Swedish, Ukrainian.
2 wing-mounted gimbals × 3 co-pointed band-dedicated masts + 1 dorsal DOM = 7 masts total. Cluster mass 1.22 kg, peak 70 W TX, 74 W EMCON-2 average at 30% duty cycle.
Bands per gimbal
Mast A operator-selected military (70 MHz–6 GHz), Mast B static-hop civil FHSS (868/915 MHz + 2.4 GHz), Mast C civil LTE/5G (700–2600 MHz) behind sealed wartime fuse.
Doctrine
200% offensive / 200% relay / 100/100 split reconfigurable per mission via MAVLink parameter. Two independent bearings engaged simultaneously.
ROE enforcement
Physical sealed fuse per Mast C (2 per airframe). Broken only by authorised officer in declared wartime zone. PAL-principle applied from nuclear weapons safety engineering.
Profile rolling
Daily YAML profile loaded via USB by operating force pre-flight. Open format, hobby-workshop doctrine. Derived from Ukrainian EW practice since 2023.
NEW: Three-tier altitude architecture
Tier 1 — Fischer 26
300 m AGL, close ISR + FPV mesh relay. Above AK-family small arms. Expected lifetime 20–40 flights.
Tier 2 — Fischer 26E
500–700 m AGL, EW + persistent ISR over FLOT. Above PKM envelope. Expected lifetime 30–50 flights.
Tier 3 — Fischer 26E-LE
~1000 m AGL stand-off, 3–5 km behind FLOT. Above practical FPV ceiling. Expensive airframe held back from densest threat concentration. Expected lifetime 30–50 flights with countermeasures.
NEW: Three-tier procurement structure
Tier A — Chinese/Ukrainian combat-proven
AliExpress, LCSC, 1688.com, Taobao. Fischer 26 €1,100–2,000; cluster €2,000–3,500 single-unit. The Ukrainian combat-proven supply chain since 2022.
17% reduction at 10 units, 40% at 50, 60% at 500. Applied identically across all hardware tiers.
NEW: Ukraine-as-innovation-hub doctrine
Empirical basis
Tier A pricing reflects what Ukrainian brigade workshops actually pay in 2026 to build drones at 100+ per week rates.
Iteration velocity
Prototype to serial production in weeks, operator feedback absorbed in days, redesigns when Russian countermeasures adapt in months.
Sourcing pattern
Nordic procurement evaluated: Ukrainian OEM with Western specification, acceptance-tested by Western authority. 30–50% of Western-prime-contractor cost.
Unresolvable constraint
Ukrainian wartime export controls, 12–18 month framework lead time. Tier A is validated in active combat; Western alternatives validated against expected threat models in test ranges.
Components resistant to Chinese substitution
Starlink Mini (SpaceX-only), Silvus StreamCaster (ITAR), Jetson Orin Nano (67 TOPS envelope). All other Fischer 26 components have functioning Chinese equivalents.
NEW: Expendability equation — CPFH and lifetime together
Tier A contested 30 flights: €34.4/hr; Tier A countermeasures 40 flights: €26.4/hr; Tier B 50 flights: €40.6/hr; Tier C 50 flights: €190.6/hr; AJS 37 Viggen baseline: €12,000/hr.
Best ratio vs manned ISR
1/455 at Tier A with countermeasures (40 flights lifetime).
NEW: LE energy budget — 10-target engagement analysis
10 targets × 1 min/target (FPV-class)
15 min engagement, 41 Wh, 4 h 48 min summer / 4 h 02 min winter.
10 targets × 2.5 min/target (median)
30 min engagement, 92 Wh, 4 h 40 min summer / 3 h 55 min winter.
10 targets × 4 min/target (Orlan-10-class)
45 min engagement, 144 Wh, 4 h 33 min summer / 3 h 49 min winter.
Energy as constraint?
No. Worst case is 7.2% of usable battery. Limits are gimbal slew time, CAN-FD throughput, operator cognitive load. 3 full 10-target batches per 3-hour winter mission.

Edition 2026-Q2 (v2.0) — Superseded
Complete rebuild from scratch. New build system (Python, zero inline styles), new CSS design system (5 modular files), new i18n string system (138 keys, 3 languages). 83 pages across 7 clusters. Lisa 26 AI Decision Engine introduced. Fischer 26 ISR platform documented. All content field-verified or marked theoretical. Four automated validators (SEO, quality gate, briefing, schema).
Edition 2025-Q3 (v1.0) — Deprecated
Original wiki. 185 independent HTML files, no build system, 5613 inline styles, machine-translated Swedish and Ukrainian. CSS patched 4 times leading to 105 duplicate selectors. Abandoned due to unmaintainable codebase. See v1 Post-Mortem for full analysis of 15 architectural mistakes.
Planned: Edition 2026-Q3 (v2.2)
Formal provable_claims.py proofs for the new 2-gimbal cluster architecture (cluster total weight, two-gimbal assignment latency, jamming ranges per band, fuse count, cost tiers, 10-target engagement energy). Additional interactive tools: Lisa 26 COP simulator, Fresnel zone calculator, stand-off coverage planner. Performance optimisation for low-bandwidth connections. Potential Finnish (FI) and Norwegian (NO) translations.
