Fairly self explanatory really. Frigates are typically (although not exclusivly) anti submarine platforms. They are sometimes armed with limited A-A capability, but specifically they but do have sonar sensors, anti submarine torpedoes and an ASW helo also with sonar sensors and anti submarine torpedoes.

Perhaps this platform could be added (with ASW helo probably a modified version of the existing AEW&C helo the carrier can get) to act as a cheap ASW escort to support surface groups?
