The AgustaWestland CH-149 Cormorant is the Canadian Forces designation for the AgustaWestland AW101 (formerly EH101), a helicopter used for air-sea rescue in Canada. Developed as a joint venture between Westland Aircraft in the UK and Agusta in Italy (now merged as AgustaWestland), the EH101 is a medium-lift helicopter for military applications but also marketed for civil use.

In 1977, the British Ministry of Defence issued a requirement for an anti-submarine warfare (ASW) helicopter to replace the Royal Navy's Westland Sea Kings. Westland responded with design WG.34 that was approved for development. Meanwhile, the Marina Militare (Italian Navy) was also seeking a replacement for its (Agusta-built) Sea Kings, leading Agusta to discussions with Westland about the possibility of a joint development. This culminated in the joint venture being finalised in November 1979 and a new company (EH Industries) being formed to manage the project the following year - EH being an abbreviation for Elicottero Helicopter the English and Italian words for "helicopter." As the design studies progressed, EH became aware of a broader market for an aircraft with the same capabilities required by the British and Italian navies, leading to a more generalised design that could be customised. After a lengthy development, the first prototype flew on October 9, 1987.
Following the lead of the UK and Italy, the Canadian government placed a $4.4 billion order in 1987 for 48 (later 42) EH101s to replace the Canadian Forces's Sikorsky CH-124 Sea Kings and Boeing Vertol CH-113 Labradors. These were to be assembled in Canada under the designations CH-148 Petrel (33 originally, reduced to 28) and CH-149 Chimo (15) in the anti-submarine warfare and air-sea rescue roles respectively. The whole programme was cancelled, however, after a change of government in 1993, leading to the payment of $500 Million in cancellation penalties.
In 1998, the Canadian government announced that the CH-113s would now be replaced by a new scaled down search-and-rescue variant of the EH101, carrying the designation CH-149 Cormorant. Unlike the Petrel/Chimo contract, these 15 aircraft were to be built entirely in Europe. The first two aircraft arrived in Canada in September 2001 and entered service the following year.
When it became obvious that the Sea Kings were in need of immediate replacement, the EH101 was again part of a Canadian competition (the Maritime Helicopter Project), against a variant of the Sikorsky H-92, for a total price tag of $5 billion. The Sikorsky entry won the competition on July 23, 2004, and the first Sikorsky CH-148 Cyclone flew in 2008.
The first operational CH-149 flight occurred in 2002 when a Cormorant of 442 Squadron performed a medical evacuation from a merchant ship 200 km (110 nmi) offshore in Hecate Strait. An even more dramatic demonstration of Cormorant capabilities occurred in late 2002 when a 103 Squadron CH-149 successfully flew a 1,200 km round-trip rescue mission to a container ship off Newfoundland. Two refuelling stops at the Hibernia oil platform were required.
On October 25, 2006, a search and rescue crew from 442 Squadron in Comox, B.C. conducted a rescue from the side of a cliff in a box canyon with the CH-149 Cormorant which Canadian Forces Captain Sean Morris described as "pretty much the worst situation I've been in my entire life." Captain Morris and his colleagues received international recognition for the rescue as the first Canadian winner of the Prince Philip Helicopter Rescue Award issued by the Guild of Air Pilots and Air Navigators in the UK [1]
In August 2010, the Canadian Forces fleet of 14 CH-149 Cormorants passed 40,000 operational hours. The fleet had a higher flying rate than any other AW101 fleet and Cormorant 901, currently stationed at Canadian Forces Base Comox with 442 Squadron, has the highest number of airframe hours on any of the AW101s anywhere in the world. The worldwide fleet of 190 Aw101 helicopters had achieved in excess of 200,000 flight hours in Canada, UK, Italy, Denmark, Portugal, and Japan.[2]
In June 2011, several US VH-71s, which are also based upon the AW101, were purchased by Canada to be used as spare parts for the CH-149 fleet.[3]
Note: CH-149 from 424 Squadron were replaced by CH-146 Griffons
