Changing sensors on Canada's Type 26 frigates

How quickly could Canada replace Aegis with a Royal Navy sensor fit on its Type 26 variant?

It could be done only with significant redesign, because a different high-end sensor suite would change both air-defense performance and hull stability.

A standard British Type 26 sensor fit would not provide the air-defence capability intended for Canada's version. A Type 45-style suite could be fitted in principle, but its weight and position would change the hull's stability requirements. Its separate radar units would also need space and integration work. Replacing Aegis would require decisions about missiles as well as sensors, with an existing British weapons suite proposed as the most practical way to limit delay. A French alternative would introduce another integration problem. Japanese sourcing for Aegis is also raised as a possibility, although the procurement consequences remain unresolved. Reducing dependence on one supplier would take time, and changing the system this late would carry substantial costs.
