OK, lets have a quick summary!
This is a Russian twin-jet aircraft built and flown. Yes
Needle nose maybe not quite as pointy as it looks, but that's how the silhouette shows it!
straight wing Yes (viewed from above
Carried comrades into battle? It didn't enter service
Not an RPV
Take a closer look at the wing-tips mate (they're not fuel tanks)
Edit:
Not a parasite project and it is/was quite large!
