[It will be 50 years for the Sea King in 2013 and sadly Sikorsky will barely be starting their deliveries of a watered down version of the product they contractually agreed to deliver. It is an affront to Canadians and I believe that Sikorsky is better than that.]
The latest from Sikorsky is that they hope to deliver two interim Cyclones to Shearwater this month (April 2012) and a further two by the beginning of June. These aircraft are expected to remain under Sikorsky title (i.e. not accepted yet by the customer) for several months. Sikorsky Cyclone #806 that has been hangared at Shearwater since May 2011 is being returned to Sikorsky facilities in the US. The four interim aircraft to be delivered soon will be used for the first serial of aircrew and groundcrew initial cadre training (ICT) but it is anticipated that they will still have significant operating restrictions. Bear in mind that this is unofficial forward-looking information at this time and is subject to change (eg. further delay).
