In 1975, the Buffalo dropped its tactical transport role and was converted to domestic search and rescue, except for a few that kept serving on UN missions. The initial paint scheme for the SAR converted aircraft were white and red while others still had the original drab paint. The previous drab paint and white paint were eventually replaced with the distinctive yellow and red scheme commonly seen today. The number of aircraft have been reduced to eight, with six on active service, one in storage (recently dismantled) and one used for battle damage training. The remaining operational Buffalos operate in the Search and Rescue role for No. 442 Squadron at CFB Comox. Air Command was renamed the "Royal Canadian Air Force" in 2011, meaning the CC-115 has served with the RCAF, Air Command and now the RCAF once again. The Buffalo was replaced by the CC-130 Hercules aircraft at search-and-rescue bases in CFB Greenwood and CFB Trenton. As early as 2002, Canada has tried to replace both the Buffalo fleet and the SAR Hercules fleet with a newer aircraft. For some time, the Alenia C-27J Spartan was seen as the likely replacement, with the government considering sole-sourcing the new aircraft. However, after changes in Canada's defense budget as well as accusations of bias from the aerospace industry, the Buffalo replacement program was relaunched as an open competition. After review from the National Research Council, the Department of Defense as well as consultation with the Canadian aerospace industry, a request for proposal was published in 2015. Bidders included Alenia offering the C-27J Spartan, Airbus Defense and Space with its C-295 and Embraer with its KC-390. In 2016, the Department of Defense awarded Airbus a contract for 16 C-295s with delivery scheduled to begin in 2019 and running through 2022.
