OTTAWA - The Canadian Press has learned the Harper government's plan to buy new fixed-wing search-and-rescue planes has been delayed yet again.

The Defence Department is not going to issue a tender call to replace nearly 50-year-old C-115 Buffalos and C-130 Hercules transports until the spring of 2013.

The 3.1-billion dollar program has now been delayed almost a decade.

A 2010 air force assessment underscored the dire consequences of the repeated delays by warning that search-and-rescue capability could be imperilled if a contract wasn't in the pipeline immediately.

National Defence is facing cuts in the March 29th budget, but a spokesman for Associate Defence Minister Julian Fantino says the government remains committed to buying new search and rescue planes.
