Yep, a twin seat SU
So a predecessor of the swing wing SU
-7 was a large tactical ground attack fighter for Soviet Frontal Aviation (a Russian TAC).
Basically similar in role to the F-105.
Primarily a platform for carrying tactical nuclear weapons, it had very limited conventional weapons carrying ability (two centre fuselage pylons for tactical nukes or more usually twin drop tanks, two wing pylons for bombs or rocket pods), a limited internal fuel capacity, but two hard hitting 30mm cannon in the wing roots.
-7's had four wing pylons.
It's virtues were it's very strong construction, simplicity, good low level performance.
It was widely exported to the Mid East and India, Indian pilots reportedly liked their big SU
-7's and rated it against hostile fighters at low level, like many of the Mid East customers, they were used in combat.
-7 was part of a family of large supersonic fighters from the Sukoi team, along with the contemporary SU
-9 and SU
-11 delta interceptors, basically the same fuselage with a delta wing, air intercept radar and AAMs (no guns), for the IA
-PVO air-defence forces.
-9 had a very short service life, as reportedly it's radar/AAM systems were compromised by espionage, though the AA
-1 beam rider AAM's were soon obsolete anyway, SU
-11 had improved avionics and AA
-3 missiles, these aircraft were pure bomber destroyers for defending the USSR
-7 and SU
-9/11 all featured a single large, thirsty turbojet.
From the late 60's, SU
-7 was developed into the far more capable swing-wing SU
-20/22 series, with much better airfield performance and warload/radius, improved engines and avionics.
-9/11 were replaced by the SU
-15, a whole new aircraft with a radar nose, side fuselage intakes, twin engines, but their only 'kill' was to be the KAL 747 in 1983.
