The Canadian Surface Ship also known as the Canadian Surface Combatant will see two contracts, with one for a Warship Design (WD) contractor and second for the Combat System Integrator (CSI).
The warship's design will have at minimum the following features:
A length of 90 metres
Surface to air missiles,
Surface to surface missiles,
A naval gun larger than 56mm.
Furthermore, the warship will have a hull mounted sonar or towed sonar array; torpedoes be capable of supporting at least 1 maritime helicopter; [ 2 Helicopters is the preferred option.]
The potential WD must be a prime or sub-contractor for a NATO Government, with a successful and proven major warship design and construction history.
The CSI bidder (I believe Lockheed Martin Canada will be chosen) must have designed, integrated and delivered the command and control software, networked processing, display surface warfare, anti-submarine warfare, long-range, surveillance and fire-control radar suites for a surface combatant of at least 90 meters.
Likely Warship Design:
The Danish Iver Huitfeldt appears to be the most likely candidate. It has an APAR, SMART-L radar and CEROS-200 fire control systems. Fires the ESSM and SM-11A AAW missile's, and Harpoon ASCM's.
The Iver Huitfeldt Class frigates have all been shock tested in accordance with NATO STANAG 4137 yet while the hull design combines both a wide beam for stability, and excellent sea keeping performance concerns regarding survivability remain, due to commercial versus military construction practices.
