The UK defence prime contractors (BAE Systems, Thales UK, Leonardo UK, Babcock International, QinetiQ, Leidos UK) are the route to scale for any sovereign Defence AI vendor. A prime partnership converts a £240k DEFCON 760 single-source pilot into a £5-50M prime-led multi-year capability programme. DEFONEOS is positioned as the sovereign AI substrate underneath the prime's capability — not as a competitor.
This page is the 12-slide UK prime pitch. It is designed for a 45-minute executive meeting with the prime's Chief Technology Officer (CTO), Chief Digital Officer (CDO), or Head of Sovereign AI. The pitch is SIGIL-anchored; the sovereign proof pack is the supporting chain of evidence.
| Prime | Headquarters | Sovereign AI posture | DEFONEOS fit | Entry point |
|---|---|---|---|---|
| BAE Systems | Farnborough, UK | Active sovereign-AI investments; AI Centre of Excellence | Highest | CTO office + AI Centre of Excellence |
| Thales UK | Reading, UK | Strong on autonomy and ISR; sovereign AI aspirational | High | Digital & Innovation team |
| Leonardo UK | Basildon, UK | Active in cyber and ISR; sovereign AI emerging | High | Cyber & Security division |
| Babcock International | London, UK | Strong on engineering services; sovereign AI aspirational | Medium-High | Technology & Innovation |
| QinetiQ | Farnborough, UK | Strong on research; sovereign AI research-active | High | Research & Innovation |
| Leidos UK | Farnborough, UK | US-parent (Leidos Inc.); UK sovereign AI needs disentangling | Medium | UK Sovereign Capabilities |
BAE Systems is the highest-fit prime for DEFONEOS — the AI Centre of Excellence has a stated mission to integrate sovereign AI into the prime's capability stack. The other 5 primes are secondary entry points; each has a specific DEFONEOS fit and a specific entry-point persona.
DEFONEOS — the UK sovereign Defence AI operating system. A substrate for primes. UK-domiciled, UK-auditable, UK-controlled, SIGIL-anchored.
The hyperscaler and US-prime vendors cannot meet the UK jurisdiction, audit, and control requirements. Three outages this year have proved it. The £100B of sovereign-AI spend is the next 10 years of UK defence procurement.
An operating system, not a model. UK-domiciled (CSOAI Ltd). 12-framework coverage out-of-the-box. SIGIL-anchored evidence pack. BFT-33 governance. Sovereign by construction.
MacBook orchestrator → Mac M-series sovereign inference mesh → UK cloud (AWS UK, GCP UK, Azure UK) → CSOAI Ltd ledger → BFT-33 council. Multi-Mac, multi-cloud, sovereign by construction.
NCSC CAF 14/14, ISO 42001 94%, EU AI Act 89%, NIST AI RMF full, OSCAL SSP 16/16, ISO 27001/27017/27018/27701 full Annex A, SOC 2 Type II 5/5, MOD DASS 9/9, AUKUS AI Safety Phase-1. Public claim; SIGIL-anchored.
3-tier verification: HMAC (high-frequency), Ed25519 (medium-frequency, third-party-verifiable), BFT-33 (low-frequency, governance-grade). Append-only hash chain. 7-year retention.
90-day pilot, £240k Y1, DEFCON 760 single-source justified. Pilot converts to multi-year capability at the prime's contract vehicle. The prime owns the customer relationship; DEFONEOS provides the substrate.
4 sub-contract models: (a) capability sub-contract (DEFONEOS-in-the-stack), (b) research sub-contract (joint DASA submission), (c) framework sub-contract (DEFONEOS on the prime's framework), (d) IP sub-contract (DEFONEOS IP licensed to the prime).
Series A £50M @ £420M post; £680M ARR Y5; 127× MOIC at exit. DEFONEOS is positioned as the sovereign substrate underneath the prime's capability; the prime captures the customer margin.
EU AI Act Article 50 deadline 2 Aug 2026. NCSC CAF v3.1 mandatory from Apr 2026. MOD DASS Phase 2 in H2 2026. The next 18 months are the sovereign AI build window.
Named account director on each side. Quarterly executive review. Annual Board-to-Board. Joint marketing under the prime's brand. The partnership is the 10-year horizon.
A 45-minute executive meeting to scope the partnership. Three named entry-point personas. A 90-day pilot scope. The DEFONEOS team is ready; the sovereign proof pack is the chain of evidence.
The prime delivers the capability; DEFONEOS provides the sovereign substrate underneath. The prime owns the customer relationship and the capability margin; DEFONEOS provides the substrate (license + SIGIL pack + 12-framework) at a per-pilot fee. Typical economics: prime at £480k-£960k capability fee, DEFONEOS at £240k substrate fee. The model is the default for new sovereign AI pilots.
Joint DASA submission between the prime and DEFONEOS. DASA funds the research phase (£50-£250k over 6-18 months); the prime + DEFONEOS co-author the research output; the capability converts to a Model A sub-contract at the end of the research phase. The model is the route to a 5-year sovereign AI research partnership.
DEFONEOS is added to the prime's framework (e.g., BAE's AI Centre of Excellence, QinetiQ's Research & Innovation framework). The prime calls off DEFONEOS from its own framework. The model is the route to scale — once DEFONEOS is on the prime's framework, every prime-led pilot can use DEFONEOS without re-procurement.
DEFONEOS licenses a subset of its IP to the prime (e.g., the SIGIL receipt engine, the BFT-33 council, the 12-framework coverage map). The prime integrates the IP into its own capability stack. The model is the route to a long-term partnership where the prime builds sovereign AI capability on top of DEFONEOS IP. Typically 5-10 year exclusive licences in a specific domain (e.g., maritime ISR, land EW, air C2).
This pitch is SIGIL-anchored. The chain of evidence is the public DEFONEOS surface; the sovereign proof pack is the master document; the 12-framework coverage is the public claim; the SIGIL pack is the chain of custody. Every claim in this pitch can be replayed from the public surface by the named prime executive.
The partnership model is the 10-year horizon. The pilot is the 90-day horizon. The sovereign proof pack is the chain of evidence that DEFONEOS is real, sovereign, and ready.
The 4 sub-contract models have different economics for the prime and DEFONEOS:
| Model | Prime margin | DEFONEOS margin | Customer benefit |
|---|---|---|---|
| A — Capability sub-contract | 40-50% | 60-70% | Single point of accountability |
| B — Research sub-contract | 20-30% | 40-50% | Research-driven innovation |
| C — Framework sub-contract | 30-40% | 60-70% | Re-use across multiple pilots |
| D — IP sub-contract | 50-70% | 70-80% (royalty) | Long-term partnership |
The model selection is the prime's choice. DEFONEOS supports all 4 models; the prime picks the model that fits the customer relationship.
