If Boeing starts up production of the OV-10 again, they could make modifications to make it more ship-friendly, couldn't they?
Either bigger motors, better high lift devices for LHD ops, or a tow bar and tailhook for CVN ops? I imagine the tow bar and tailhook might be stretching it, even though it seems to have pretty beefy gear.
Seems reasonable, no?
From an engineering standpoint, these mods are very much non-trivial.
You can't just have a monkey with a welder tack on a tailhook and some bigger tires. Making any of your proposed changes means a massive re-design and test effort.
Seems to me that if we're bringing back a 40 year old design, it's to save money, not take it and essentially make a new aircraft from it anyway.
