The example divides an air-defence system between one ship carrying the large radar and another carrying its missiles. Losing the radar ship would deprive the missile ship of the sensor it needs; losing the missile ship would leave the radar without that weapon capacity. Putting both functions aboard each of two larger ships preserves a complete combination after either ship is lost. The criticism concerns mutually dependent specialist hulls and the assumption that distributing their functions automatically improves survivability.

Why separating radar and missile ships can create a dependency
A two-ship example tests the survivability of splitting sensors and weapons between mutually dependent hulls.
