So yeah, this just buzzed around in my mind. What if Canada didn't screw around on ordering those Iroqouis replacements?
Basically a lenghtened LCF, the main differences are the 64 cell VLS, the replacement of the 8 Harpoon canisters with 2 8 cell MK-41 self-defense lenght VLS filled with ESSM, and the WR-21 gas turbines replacing the Spey engines. Together with a redesigned gearbox the extremely efficient WR-21 gas turbines give the Tribal class a rather huge increase in range.
Apart from accomodating the extra weapons, the lengthening of the ship almost exclusively adds to the ships bunkerage and storage, to make the operational range and duration desired by the Canadian navy. The flight deck has been widened and lengthened, and a Bear Trap sytem has been fitted.
The only other real difference than was that the hull was partially made out of thicker gauge steel, to accomodate operations in the extreme northern parts of Canada's waters, with the shipyard preferring to use as much of the original LCF design as possible to lower design costs.
The APAR array is fitted to a Thales-Samsung I-Mast, and the SMART-L sits a few feet higher.
