Has anyone ever heard of a plane SR-75, a replacement for the 71?

markwillstar asked:


When i was young i built a model airplane of a replacement for the SR-71 called the SR-75 Penetrator (i think was the name).

It had the same body shape, but carried at least 2 pilots maybe 3.

It also had flat wings and up turned ends.

Instead of the nasal engines it had B1 type box engines under the wings.

does this plane exist?
