It will also provide tactical transport for national and international security efforts. The process to acquire a replacement for the Sea King originally began in 1992. Delivery of the 28 CH-148s ordered with full capability is to be completed in 2013.

Development

The Canadian Forces' Maritime Helicopter Project (MHP) was commissioned during the 1980s and initially selected a variant of the AgustaWestland EH-101. After a change of government, the EH-101 contract was cancelled in 1993, resulting in a 10-year delay to the procurement of a replacement aircraft. The project took on increased importance in the early 2000s and another procurement competition was initiated.

 announced the award of a C$1.8 billion contract to Sikorsky to produce 28 helicopters, with deliveries scheduled to start in January 2009.

In addition to Sikorsky, General Dynamics Canada and L-3 MAS, Sikorsky's subcontractors, are responsible for in service maintenance. This includes the Maritime Helicopter Training Centre, with two Operational Mission Simulators. Other elements of in-service support include the Integrated Vehicle Health Monitoring System, spares and software support.

The first flight of the first production CH-148, serial number 801 (FAA registration N4901C), took place in Florida on 15 November 2008.

Delays and upgrades

In May 2010, Sikorsky announced an engine upgrade for the CH-148 Cyclone by the end of 2012. General Electric is developing a new engine version based on the CT7-8A1. The CT7-8A1 makes the CH-148 Cyclone heavier and less efficient than expected. General Electric is currently developing the CT7-8A7 to be certified by June 2012 and eventually integrated into the Cyclone as soon as possible. General Electric will develop the upgraded engine at its own expense. The new CT7-8A7 engine version will produce 10% additional horsepower. The CT7-8A7 will include modifications to the fuel manifold and nozzles. The interim CH-148s will be provided with CT7-8A1 engines.

Design

The CH-148 has a metal and composite airframe. The four-bladed articulated composite main rotor blade is wider and has a longer radius than the S-70 Blackhawk. The tapered blade tip sweeps back and angles downward to reduce noise and increase lift. Tethered hover flight has recorded 138 kN (31,000 lbf) of lift generated, both in and out of hover effect.

Operational history

The Canadian Forces were to take delivery of CH-148s beginning in November 2008. In April 2009 the Government of Canada waived late fees and allowed Sikorsky two additional years to deliver compliant Cyclones. In February 2010, the first CH-148 arrived at CFB Shearwater

In June 2010, Sikorsky announced the Canadian Forces would receive six interim CH-148 Cyclones in November 2010. In July 2010 the Canada and Sikorsky reached an agreement on delay payments and deliveries. Delivery of the remaining CH-148s with full capabilities are to begin in June 2012. All interim-standard helicopters are to be retrofitted by December 2013.

On 22 February 2011, the Office of the Prime Minister of Canada announced the proposed arrival of 9 Cyclones on Canada's west coast in the spring of 2014.

By March 2011 the six interim CH-148s had not been delivered. On 3 March 2011, the federal government announced that it would impose a fine of up to C$8 million on Sikorsky for failure to meet contractual obligations.
