Could a Bear-F shoot down a P-3 Orion?

Is the mount in the Bear-F's tail a twin 23 mm gun, and does the P-3 Orion have comparable defensive armament?

Yes, the Bear-F has the twin 23 mm tail mount, while the P-3 lacks comparable defensive guns, making it one of the unusual aircraft the Soviet patrol plane could plausibly threaten directly.

The visible tail installation on the Bear-F is a twin 23 mm mount. The P-3 Orion has no comparable defensive gun position in this exchange. That asymmetry makes a close encounter more than a photographic curiosity. Although the Bear's main value here is reconnaissance, its tail armament could threaten an unarmed patrol aircraft that remained too close.
