AAW2 (anti-air warfare)

AAW2 is the NATO abbreviation for anti-air warfare. NATO's glossary of acronyms and abbreviations expands AAW2 as "anti-air warfare" and cites the allied publication ATP-01 as its source. The term belongs to naval warfare, where it describes the defence of ships and maritime forces against threats from the air.

The Canadian Armed Forces define anti-air warfare as the measures taken to defend a maritime force against attacks by airborne weapons launched from aircraft, ships, submarines and land-based sites. Canadian documents usually write the term as AAW, while the NATO glossary uses the numbered form AAW2 to keep it separate from a similar abbreviation, AAW1.

How NATO records AAW2 and separates it from AAW1

The NATO abbreviation glossary, published as AAP-15, lists two entries that look alike. AAW1 stands for "air-to-air warfare". AAW2 stands for "anti-air warfare". The number is part of the abbreviation and tells the reader which expansion applies, so the two should not be used interchangeably.

NATO's wider terminology is held in NATOTerm, the official database of non-classified military terminology. It is maintained by the NATO Terminology Office within the NATO Standardization Office.

The Canadian Armed Forces definition of anti-air warfare

The Royal Canadian Air Force doctrine glossary defines anti-air warfare as measures taken to defend a maritime force against attacks by airborne weapons. It names four launch points: aircraft, ships, submarines and land-based sites. The definition is about protecting a force at sea, not about attacking aircraft for their own sake.

The matching abbreviations list sits alongside the glossary in the same doctrine publication.

Where AAW sits among maritime warfare areas

Canadian aerospace doctrine, in chapter 3, names anti-air warfare as one of three maritime warfare areas. The other two are antisurface warfare and underwater warfare.

The same doctrine describes AAW operations as intended to destroy or reduce an adversary's air and missile threat. They also protect maritime forces, high-value units or other vital assets from attack from the air.

Counter-air operations and the air force usage

The Canadian glossary adds a point of vocabulary. In an air force context, AAW is synonymous with counter-air operations. A reader moving between naval and air force documents will therefore meet the same idea under two names.

A Canadian defence research publication, D68-1-61-2014, also uses AAW as the abbreviation for anti-air warfare. It does so when discussing naval complex sea days and training measures.

What AAW2 means for a supplier bidding on Canadian public contracts

Canadian Armed Forces and Government of Canada documents use the form AAW, while the NATO glossary uses AAW2. A bid team should read both as the same warfare area, anti-air warfare, and should not confuse either with AAW1, which is air-to-air warfare.

Requirement wording varies by solicitation, so use the exact term and definition given in the tender documents when describing capabilities, experience or training. Where a document refers to counter-air operations, check the context, because Canadian doctrine treats that phrase as synonymous with AAW in an air force setting.
