Line drawings of the Hawker Siddeley P.139B. The AEW version (note the radar domes fore and aft) is shown in most of the views, but the freighter version is shown in the right mid profile.

A carrier capable version of the Hawker Siddeley HS.125 Dominie was considered for Carrier on Board Delivery tasks.

I did read recently that the P.139B would have been unflyable and at best a widow maker (not that that mattered to the RN of the 1960s!). If CVA01 had been built its almost enivitable that AEW would have been Gannets and then Hawkeyes when they ran out of hours.
As a though wouldn’t the Domonie have made a cracking little ASW platform, a British Viking…..?
