SAL2 (support airlift)

SAL2 is the NATO abbreviation for support airlift. It is listed with that expansion in the Glossary of NATO Acronyms and Abbreviations (AAP-15), where the source for the entry is given as NASG.

The abbreviation belongs to NATO's own vocabulary. It is not the name of a Canadian programme, and it should not be confused with SALIS, the Strategic Airlift International Solution, which is a distinct NATO arrangement for heavy air transport. Bid teams that meet SAL2 in a document should treat it as NATO terminology for support airlift.

Where SAL2 appears in NATO terminology

The entry sits in AAP-15, NATO's reference list of acronyms and abbreviations. The glossary gives the expansion, support airlift, and the source designation NASG. It does not add a longer definitional sentence, so the expansion itself is the established meaning.

NATO also maintains NATOTerm, its official terminology database for non-classified military and relevant non-military terms. NATOTerm is the place to check how NATO defines and uses its terminology more broadly.

How SAL2 differs from SALIS and strategic airlift

NATO uses several airlift terms that sound alike but mean different things. Support airlift (SAL2) is one. Strategic airlift is another, and NATO describes it on its strategic airlift page. That page also covers the Strategic Airlift International Solution (SALIS) and the Strategic Airlift Capability (SAC).

SALIS gives participating countries assured access to Antonov AN-124-100 aircraft, which can carry up to 120 tonnes of cargo. The programme is managed by the NATO Support and Procurement Agency (NSPA), as shown in NATO's account of allied airlift bringing urgent medical supplies to the Czech Republic. NATO describes NSPA as acquiring and supporting airlift services and assets for its customers.

• SAL2: NATO abbreviation for support airlift, listed in AAP-15.
• SALIS: a separate programme giving access to heavy transport aircraft, managed by NSPA.
• SAC: the Strategic Airlift Capability, a separate NATO term.

Airlift in Canadian defence doctrine

Canadian defence publications discuss airlift in general terms. The Royal Canadian Air Force's force sustainment doctrine describes air movements and airlift support as transportation functions. That document does not use the abbreviation SAL2, so the doctrine gives context for airlift but does not define SAL2 as a Canadian term.

What SAL2 means for a supplier bidding on Canadian public contracts

SAL2 is not a Canadian contract clause, certification or programme name, so there is no standard supplier action tied to it. If the abbreviation appears in a solicitation, read the surrounding text to see how the requirement is described, and check whether it is a requirement or a deliverable. Where the meaning is not clear from the document, put a question to the contracting authority in the way the solicitation directs.

Federal opportunities are posted on CanadaBuys tender opportunities. Suppliers working on airlift-related requirements should keep the NATO terms distinct in their bid documents, and should not substitute SALIS or strategic airlift wording where a solicitation refers to support airlift.
