Care to rewrite your claim?

A ten mile high (sub) orbit ?

If it could stay at ten miles, no more no less it would, be in orbit.
Can't be done, the 5 mi/sec would burn up anything eventually.
You might travel at the speed which would approximate orbit down in
the air, with big enough nuclear engines. This is flying a high speed
powered aircraft. The interior of the plane would undergo
weightlessness, juat as if it was in orbit.

Any ballistic projectile, that is one traveling under only the
influences of momentum and gravity, [and neglecting air drag,] is
technically in a sub orbit.

A battleship projectile is heavy for the drag it produces, and comes
somewhat close to being in a sub orbit. It goes about half as far as
it would in a vacuum. Average deer rifles go a tenth as far, or so.
A BB shell would reach ten miles altitude at the longer ranges.

That makes it around 60,000 feet.

Yes, for nautical miles, very close.

You got any idea what speed would be required for such an orbit?

A few thousand fps, enough to barely reach ten miles high, to just
under orbital speed of about 18 000 MPH. It depends on the range. In
the case under discussion, maybe several miles/sec. Enough to burn
like a cheap meteor, which I suppose is your point.

And well within the range of most ship based antiaircraft missiles

ICBM's are suborbital and I think most ship AA would have trouble with
them. How much warning would a ships radar give of an incoming ICBM?

Du-bang-ck!
