Various commentators have discussed the feasibility of putting the SPY-3 radar on notional frigate designs. SPY-3 is an Active Electronically Scanned Array (AESA) that, in its current US Navy guise, is an X-band radar with volume search omitted.
Here is a cost data point that may affect people’s outlooks on this. From the Navy’s FY14 budget justification document we see the cost of a single SPY-3 for the DDG-1002 is $185M ($258M with support and “other” included). That’s a big chunk of money to devote to a frigate whose main design criteria should be affordability and, hence, numbers!
I don’t know, does that change anyone’s mind?
