This involved removing the observer's cockpits and creating a new cabin within the fuselage; this was accessed via a pair of hatches next to the trailing edge of the wing, which also meant that the exhausts had to be moved from this position to the leading edge; increasing the total area of the vertical stabiliser to compensate for the instability caused by the radome; and extending the length of the undercarriage to increase the clearance for the radome, which consequently increased the aircraft's overall height by 3 feet , and gave the aircraft a more level stance than the anti-submarine version.
