DOCTRINE INDEX
TIER STRUCTURE, STAND-OFF, SYSTEM ROLES
The FSG-A wiki grew from a single Fischer 26 ISR platform description to a 109-page encyclopedia covering three airframe variants, a 20-page Lisa 26 AI decision engine, a 9-page C-UAS vehicle upgrade catalogue, a 6-page fibre-optic countermeasures cluster, and a formal SDK for Försvarsmakten system integration. Several concepts now appear on many pages — tier A/B/C pricing, 300/500–700/1000 m AGL altitude stacking, stand-off EW doctrine, the expendability equation, and the Lisa 26/GUTE II distinction. This index collects them in one place and links out to the deep-dive pages. Read this first, then follow the links that matter for your role.
1. Three-tier altitude architecture
Fischer 26 airframes operate in a three-tier altitude stack. The tiers are not redundant alternatives; they are coordinated roles. The cheap airframe overflies the forward line and accepts small-arms attrition. The expensive airframe with the antenna cluster stands off behind the line and protects the cheap ones electronically. The drone-scale version of Rafale+SCALP or F-35+JASSM-ER stand-off strike geometry, scaled down.
| Role | Which airframe | Altitude band | Mission | Lifetime bracket |
|---|---|---|---|---|
| Forward ISR | Fischer 26 | 300 m AGL overhead | Close surveillance plus FPV mesh backbone | 20–40 flights |
| Mid EW | Fischer 26E | 500–700 m AGL | Electronic warfare with persistent overwatch | 30–50 flights |
| Stand-off | Fischer 26E-LE | 1000 m AGL approx, 3–5 km rearward | Over-the-horizon jamming support | 30–50 flights |
Deep dives: Antenna cluster architecture for the stand-off asset; energy budget for endurance with the cluster online; Fischer 26E for the mid-tier variant.
2. Three-tier procurement structure
Every cost-dependent page in this wiki uses the same three procurement tiers. Tier A is not a theoretical budget option — it is the Ukrainian combat-proven supply chain since 2022. Tier B is the Western commercial baseline. Tier C is MIL-qualified hardware for formal Försvarsmakten acquisition.
TIER A / B / C SUMMARY
Deep dives: Fischer 26 baseline tier structure; antenna cluster tier structure + volume-break curve; Fischer 26E variant costs.
3. Ukraine 2026 — empirical innovation hub
The Tier A figures reflect what Ukrainian brigade workshops actually pay in 2026 to build drones at 100+ per week. The iteration cadence is in weeks, not years. Western defence acquisition cycles measure in years and cost 5–10× more. The practical implication for Nordic procurement: Ukraine should be treated as the empirical reference point for drone engineering in this war, rather than purely as a donation target.
UKRAINE-AS-HUB — KEY PARAMETERS
Deep dive: Fischer 26 whitepaper — "Ukraine 2026" section.
4. Expendability equation — CPFH and lifetime together
A single cost-per-flight-hour number misleads when the airframe's lifetime bracket is not also specified. Drones fielded by Ukrainian units in 2026 cover a broad lifetime spectrum, so the CPFH for a given procurement tier shifts depending on which bracket applies. The table below produces the €26.4/hr Tier-A-with-countermeasures figure behind the 1/455 ratio against manned AJS 37 Viggen ISR.
| Airframe category | Flights before retirement | Primary loss driver |
|---|---|---|
| FPV one-shot munition | 1 | Intentional — impacts the target |
| Tactical short-range strike/recce | 5–15 | Small arms plus EW at low altitude |
| Fischer 26-style tactical ISR+EW | 20–40 | Countermeasures, SAM, environmental |
| Fischer 26E-LE persistent platform | 30–50 | Altitude reduces ground exposure plus FPV reach |
| Baba Yaga / Shark long-endurance | 50–100+ | Wear from transport plus maintenance |

5. FSG-A is an idea generator — Lisa 26 demonstrates what GUTE II should do
This is the architectural positioning that anchors the rest of the wiki. FSG-A is not a defence vendor. We do not produce systems for procurement. We produce reference designs — runnable code, executable proofs, formal documentation — that Försvarsmakten, FMV, FOI, allied NATO authorities, and volunteer Ukrainian workshops can fork, adapt, and build on. Everything on this wiki is CC BY-SA 4.0 for exactly that reason.
Lisa 26 specifically is a demonstration of the capabilities a modern ISR/EW brigade AI decision layer needs. Its purpose is to make concrete — in running code and verified math — what "AI-assisted threat fusion with L1/L2/L3 decision authority" actually means, so that the organisations building the real system have a reference to measure against. The real system is GUTE II, procured by FMV on 2026-04-02 (SEK 8.7 billion, deliveries 2027–2028). When GUTE II reaches full operational capability, Lisa 26's role as an idea source is complete. The demonstration has done its job.
THE FSG-A IDEA-GENERATOR MODEL
provable_claims.py), formal documentation (FMEA/TEMP/ILS/Safety Case/SBOM/Threat Assessment/Interop Matrix), open hardware specifications. All CC BY-SA 4.0.libfischer26e.gute_ii module lets Fischer 26 hardware feed GUTE II tracks today — before 2027 deliveries — so brigades can exercise the full data flow in advance, using Lisa 26 as the decision layer until GUTE II's own decision layer is fielded.This matters for evaluators. An FMV acquisition officer reading this wiki should not interpret Lisa 26 as a competing product pitch. It is a capability demonstration for functions GUTE II will itself need to deliver. A FOI researcher should not treat Lisa 26 as a validation study of Nordic drone AI; it is a reference implementation, TRL 3, no flight hours, intentionally unvalidated because validation belongs to the programme that actually fields the system.

6. Reading paths by role
The 109 pages of this wiki serve different readers with different questions. Four recommended paths:

This index is a navigation aid; it does not introduce new technical claims. Every number cited here is derived on the linked deep-dive page, and every deep-dive page cites its primary sources directly. For the Lisa 26 / GUTE II distinction specifically: GUTE II's procurement basis is FMV press release 2026-04-02 (SEK 8.7 billion, deliveries 2027–2028). Lisa 26 is an FSG-A research platform, not a procured Försvarsmakten system. FSG-A has not obtained formal procurement quotes for any figure on any linked page.
