Combined Maritime Forces (CMF)

A 33-nation maritime security partnership

Combined Maritime Forces (CMF)

The Combined Maritime Forces (CMF) is a multinational maritime partnership, which exists to uphold the International Rules Based Order (IRBO) by countering illicit non-state actors on the high seas and promoting security, stability and prosperity across approximately 3.2 million square miles of international waters, which encompass some of the world’s most important shipping lanes.

What we do

CMF’s main focus areas are counter-narcotics, counter-smuggling, suppressing piracy, encouraging regional cooperation and engaging with regional and other partners to strengthen relevant capabilities in order to improve overall security and stability, and promoting a safe maritime environment free from illicit non-state actors. When requested, CMF assets at sea will also respond to environmental and humanitarian crises.

  • CMF has three Combined Task Forces: 
    • CTF 150 (Maritime Security Operations outside the Arabian Gulf)
    • CTF 152 (Maritime Security Operations inside the Arabian Gulf)

How CMF works

CMF nations are united in their desire to uphold the IRBO by protecting the free flow of commerce, improving maritime security and to deterring illicit activity by non-state actors in the CMF Area of Operations.

CMF is a coalition of the willing and does not proscribe a specific level of participation from any member nation. The contribution from each country, therefore, varies depending on its ability to contribute assets and the availability of those assets at any given time.

The 33 nations that comprise CMF are not bound by either a fixed political or military mandate. CMF is a flexible organisation. Contributions can vary from the provision of a liaison officer at CMF HQ in Bahrain, to the deployment of warships or maritime reconnaissance aircraft. We can also call on warships not explicitly assigned to CMF to give Associated Support. This allows a warship to offer assistance to CMF whilst concurrently undertaking national tasking.
