Why a four-engine Hawkeye offered little advantage

Why was a proposed four-engine version of the E-2 Hawkeye dismissed?

It added engine complexity and hangar burden without providing power that the airborne-early-warning mission needed.

The British proposal is compared with the coupled-engine arrangement used in the Gannet, but the panel sees no operational demand for that much power. More engines add maintenance and integration complexity while using scarce carrier hangar volume. Carrier aircraft must justify every increase in folded size and support burden.
