From Spruce Goose proof of concept to maritime patrol

The H-4 had demonstrated flight but still needed development before becoming an operational aircraft, with long-range anti-submarine patrol offered as one possible role.

Question

How close was the Spruce Goose to a working design, and how much more development did it need?

Short answer

It had proved flight rather than operational service; further development could turn the large seaplane into a long-range maritime-patrol and ASW platform.

Notes

The H-4's brief flight demonstrated that it could take off, but did not establish a reliable operational aircraft. No firm estimate of the remaining development is given. A participant then suggests adapting the large flying boat for long-range anti-submarine patrol, and the idea is accepted as a possible role. Its internal space prompts comparison with the Sunderland's galley and speculation about rest facilities, showers, and two or three flight crews. Atlantic patrols become a way to explore how crew endurance could benefit from a very large airframe. These are proposed uses and imagined accommodations, rather than demonstrated H-4 capabilities.
