War risk aviation insurance covers the physical loss of an aircraft and the liability of its operator arising from war, hijacking, terrorism, sabotage and allied perils that are excluded from the principal aviation hull and liability policies, written by specialist war risk markets at Lloyd’s and elsewhere.
Category: Aviation insurance Also known as: aviation war risk, AVN 52 covers, war and allied perils aviation First codified: Lloyd’s wordings from the Second World War; modern AVN 48B exclusion and AVN 52 series add-back clauses Related legislation: Civil Aviation Act 1982 [1]; EU Regulation 785/2004 (retained law) [2]
War risk aviation insurance addresses the physical damage and liability exposures arising from war, war-like operations, hijacking, terrorism, sabotage, riots, civil commotion and related perils. These perils are excluded from the main aviation hull insurance and combined liability policies by the AVN 48B war, hijacking and other perils exclusion clause, and are then ‘added back’ by separately rated war risk wordings (the AVN 52 series for hull and liability respectively) [3][4].
The market for aviation war risk cover is concentrated in a relatively small number of specialist syndicates and insurers. London Lloyd’s has historically been the dominant centre, with significant additional capacity in continental Europe (notably the Allianz, AXA XL and Munich Re aviation operations), the United States and a small number of mutuals. The market is highly sensitive to geopolitical events: a major loss or political incident can lead to rapid restriction of cover and dramatic rate increases [3][4].
The product is structured in three main forms: hull war (covering physical damage to the aircraft from war perils, normally written for the same agreed value as the main hull policy); excess war liability (providing third party and passenger liability cover for war perils, typically purchased as an excess layer above a basic war liability cover included in the main combined single limit policy); and standalone confiscation and similar political risk covers for specific exposures such as state seizure of aircraft on foreign soil [3][4].
War risk aviation insurance is a class of general insurance falling within the regulatory regime of the Prudential Regulation Authority and Financial Conduct Authority for UK-domiciled insurers, and within Lloyd’s regulatory framework for Lloyd’s-based capacity providers. There is no specific statutory framework dedicated to aviation war risk, but the cover interacts with several legal regimes [5].
The Civil Aviation Act 1982 governs strict liability for ground damage caused by an aircraft (section 76) and applies to losses arising from war and terrorism in the same way as to other causes, except where excluded by statute or by the insurance contract. The Reinsurance (Acts of Terrorism) Act 1993 enables the Treasury to reinsure terrorism risks; it has been used principally for property and business interruption insurance through Pool Re rather than aviation, but the underlying statutory framework remains potentially applicable [1][6].
EU Regulation 785/2004 (as retained in UK law) requires that the minimum insurance limits for air carriers include cover for liabilities arising from war and terrorism, except where specifically derogated by EU or domestic provision. The UK CAA accepts evidence of separate war risk cover combined with the main policy as satisfying this requirement [2][7].
Post-Brexit, the UK retains the Aviation War Risk (Insurance) Act 1939 framework (and its successor provisions) which empowers the Secretary of State to provide reinsurance to UK aviation insurers in respect of war risks in certain circumstances. This power has not been routinely invoked since the post-2001 stabilisation measures lapsed but remains in reserve for major geopolitical disruptions [1].
A commercial airline buys war risk cover as a structured set of contracts running alongside the main hull and liability programme. The basic war hull cover provides full agreed-value indemnity for war-peril losses, sometimes with a ‘war risk excess’ deductible or a limited per-occurrence sub-limit for sabotage and similar covert acts. The basic war liability cover (commonly written within the main combined single limit at a relatively low limit — historically US$50m, now often US$150m) is supplemented by an excess war liability layer providing additional cover up to higher limits (commonly US$500m to US$1bn for major airlines) [3][4].
Underwriters require detailed disclosure of route structure (with particular attention to destinations near or in conflict zones), claims experience, the operator’s security arrangements (compliance with International Civil Aviation Organization Annex 17 security standards and IATA programmes), and exposure aggregation across the war risk market. Premium is typically expressed as a base premium plus per-flying-hour or per-departure rates for routes through identified higher-risk areas, with notification requirements for changes in route structure [3][4].
The Russia-Ukraine conflict from February 2022 has fundamentally reshaped the aviation war risk market. Restrictions imposed by Russia on the return of Western-leased aircraft following sanctions left approximately 400 aircraft worth in excess of US$10bn stranded in Russia, triggering substantial claims under hull war policies and prompting litigation in multiple jurisdictions over the coverage of contingent and possessed-hull losses, the application of seizure exclusions, and the interpretation of standard war risk wordings. The losses have driven significant rate increases and material restriction of war risk wordings in recent renewal cycles [4].
Hull war: physical damage cover for war perils, normally at the same agreed value as the main hull policy.
Excess war liability: third party and passenger liability cover for war perils, in excess of the basic limit included in the main combined single limit policy.
Confiscation cover: standalone cover for state seizure of aircraft on foreign soil, particularly relevant for leased aircraft operating in politically volatile jurisdictions.
Cyber war: emerging sub-class addressing cyber attacks on aircraft systems or supporting infrastructure that meet the relevant definition of ‘war’ or ‘hostile act’. Coverage is still developing and many wordings exclude cyber unless specifically endorsed.
Aviation Hull Deductible Buy-down (War): supplementary cover for the per-occurrence deductible applicable to war risk claims under the primary hull war policy.
A UK-listed cargo airline operating a fleet of 14 widebody freighters places its 2026/27 war risk programme through specialist aviation brokers. Hull war cover is written for the same agreed values as the main hull policy (US$2.1bn fleet total) on AVN 48B/52E terms with a fleet aggregate deductible. Excess war liability of US$500m is placed above the US$150m war liability sub-limit included in the main combined single limit policy. The annual premium for the combined hull and excess war liability cover is illustratively US$3.2m, reflecting the recent hardening of the market. During the policy year a minor security incident at a continental European airport results in damage to one of the operator’s aircraft from a small explosive device, with no fatalities; the hull war policy responds for the repair costs of US$3.4m, less the fleet aggregate deductible. Figures in this example are illustrative.
