Combination of freefall armament could include:

• 200 kg of bomblets in internal bays
• 4 FAB-50 or FAB-100 bombs
• 2 FAB-250 bombs
• 2 UKhAP-250 chemical weapon containers.

Each bay could carry up to one 100-kg bomb or up to 100 kg of small fragmentary and incendiary bombs or AZh-2 incendiary ampoules, loaded from removable panels on the back of the wing and laid directly on the closed doors; to keep the bomblets in good order, up to two removable walls were installed in each bomb bay.

On Il-10, the wing armament was similar to that of late Il-2s and comprised:

2 VYa 23 mm guns, one on each wing, with 300 rounds each;

2 ShKAS 7,62 mm machine-guns .

On the right wing, outside the guns, there was the presisposition for a PAU-22 or S-13 gun camera.

The NS-20KM of later variant and B-33
 
 

Five types of rear turret and weapons were utilized on this type:

Sh-20 20 mm gun on VU-7 turret for the Il-10 prototype;

Berezin UBK 12, 7 mm machine gun on Vu-8 turret for early production Il-10s;

Berezin B-20 gun on VU-9 turret for late production Il-10s;

Berezin BNT-20 E on electrically actioned turret VU-9M on Avia B-33;

Berezin BT-20 EN on electrically actioned turret VU-9M on Il-10M.

Turrets were exteriorly identical, and were (hardly) distinguishable by the gun barrel.
 
 
 

	The VU-7 turret of the Il-10 prototype, armed with a Sh-20 20 mm gun, doesn't show esthetical differences when compared to later versions.
	The VU-8 turret of early Il-10s was armed with UBK 12, 7 mm machine gun.  Note that the gun is arranged in different way than on Il-2, where gas cylinders were over the barrel; on Il-10, all the weapon was reclined on its side to allow better visibility. The ammo box is on the side of the machine un; two furter ammo boxes are stored on the rear wall. Note that the gunner seats on a sort of belt, only marginally more refined that those of Il-2; it allows better side movements for aiming. Those weapons were provided for the external installation of a gun camera on the barrel for training purposes.
	The VU-9 turret for late Il-10, aesthetically identical, is equipped with the 20 mm B-20 gun, hardly distinguishable from UBK except for being thicker. There is only an ammo box suspended to the turret frame, and connected to the gun by a flexible ammo guide. Those weapons were provided for the external installation of a gun camera on the barrel for training purposes.
	The turret VU-9M was electrically actioned, and armed with 20 mm Berezin BNT-20 E (on Avia B-33) or BT-20 EN (on Il-10M). The ammo box arrangement was as on VU-9.

Defensive armament also included ten AG-2 parachuted aviation grenades in a DAG-10 container installed in the aft fuselage. This device, installed on early Il-2s and usable both against pursuing planes and against infantry, was discontinued on late production Il-10s. It was sometimes present on B-33s too. It fired through a slot under the right wingroot fillet. Image from Il-2 type 3 and Il-10/avia B-33 in detail, WWP

An AFA-IM camera for aerial photography was installid in the lower part of rear fuselage. It took shots through a window closed by small doors.

Il-10 was provided with up to 4 rails for rockets RS-82, RS-132 and ROFS-132, 2 under each wing outer panel.

Below right: the only rail of another plane preserved in poland. The firing cable is clearly visible at the rear end of the rail.

According to some sources, the wing armament of Il-10s was replaced with 4 NS-23 guns with 150 rounds each; I have not photographic evidence of this modification, that could easily be mistaken for Czech-built B-33.

B-33 was a Czech-built version, built in 1952-1955 in about 1500 pieces and exported to Poland, Hungary, Romania, Bulgaria and Yemen

was armed with:

• 4 wing-mounted NS-23KM (or RM) instead of 2 VYa and 2 ShKAS of the Soviet version; these guns have their barrels protruding from the leading edge; outer guns were in slightly lower position than inner guns.
• VU-9M turret instead of VU-9, armed with BNT-20E (B-20) 20 mm gun instead of the VU-8 or 9 of the Soviet version;
• 4 2RU-324 racks for four czech N-150 rockets or, as an alternative, 2 LR-130 rockets installed in two JRRO launch tubes under the wings;
• bombs, as the Soviet version.

Apart for the wing guns, the B-33 could be distinguished from Il-10 because of her radio mast, slightly bended forward instead of vertical.
 
 

CB-33, a Czech-developed trainer markedly different from Soviet Il-10U, could have four, two or none wing guns.
 
 

Il-10M, an enlarged version built in 1952-1954 in about 136 examples, was armed with:

4 NR-23 with 600 rounds each instead of the previous wing armament;

VU-9M turret, electraically-powered, replaced the VU-8 and 9; it was equipped with one BT-20EN 20 mm gun, with 150 rounds;

bombs as the original version, plus two racks under the outer wing panels, between the guns, able to load furter 2 x 250 kg bombs or auxiliary tanks.
