Also known as

- OCC 90 62
- OCC 90-62
- OCC 90 F1
- OCC 90 F2

- 90 mm CN90F1 HEAT projectile
- French 90 mm HEAT-T projectile
The 90 mm HEAT projectile is a French high-explosive anti-tank tracer round family associated with GIAT 90 mm light vehicle guns, especially the CN90F1 / DEFA D921 on AML-90-family turrets. Public ammunition references identify OCC 90-62 and related OCC 90 F1/F2 listings, while Nexter/MECAR documentation ties the later M630 service and M653 training-practice rounds specifically to CN 90 F1 guns.

Variants
Public sources expose the same French 90 mm HEAT family through legacy OCC designations and later Nexter/MECAR catalog labels, so the row names below separate sourced identities from broader family context.
| Variant | Configuration | Designation notes |
|---|---|---|
| OCC 90 62 | French HEAT-T projectile designation | The JMU projectile guide lists the French 90 mm HEAT-T OCC 90 62 projectile and gives a 670 g net explosive weight. Sources: JMU projectile guide |
| OCC 90-62 | Nexter Munitions HEAT-FS designation | Forecast International lists OCC 90-62 as a 90 mm high-explosive anti-tank fin-stabilized round under Nexter Munitions. |
| OCC 90 F1 | Nexter Munitions HEAT-T designation | Forecast International lists OCC 90 F1 as a 90 mm high-explosive anti-tank tracer designation in the Nexter Munitions line. |
| OCC 90 F2 | Nexter Munitions HEAT-T designation | Forecast International lists OCC 90 F2 as a second 90 mm high-explosive anti-tank tracer designation in the same Nexter Munitions group. |
| 90mm F1 HEAT-T M630 | MECAR service HEAT-T round | The Nexter 2016 catalog describes M630 as a fixed 90 mm HEAT-T round for current in-service CN 90 F1 (DEFA) guns. Sources: Nexter 2016 catalog excerpt |
| 90mm F1 HEAT-TP-T M653 | MECAR training-practice round | The Nexter catalog describes M653 as a fixed 90 mm HEAT-TP-T training-practice round designed to match the ballistics of the in-service M630 HEAT-T round. Sources: Nexter 2016 catalog excerpt |
Firing Weapons
Source references for the AML-90's gun family identify this projectile class as HEAT ammunition fired by the 90 mm vehicle gun.
| Firing weapon | Weapon type | Firing evidence |
|---|---|---|
 | Armored car with 90 mm gun | Army Guide says the AML-90's GIAT 90 mm F1 gun fires HEAT projectiles, and Military Periscope likewise says the CN-90-F1 tank gun fires a HEAT projectile. Sources: Army Guide AML 90 modernization, Military Periscope 90-mm CN-90-F1 overview |
 | BTR-60 fire-support conversion with AML-90 turret | Oryx documents BTR-60s with AML-90 turrets in Yemen's pre-war vehicle inventory, and Army Guide documents HEAT projectiles for the AML-90's 90 mm F1 gun; this is a compatibility relationship, not proof that the projectile was fired in Yemen. Sources: Handbook Of Pre-War Yemeni Fighting Vehicles, Army Guide AML 90 modernization |
 | Improvised tracked vehicle with AML-90 turret | Oryx documents an M113 with AML-90 turret in Yemen's pre-war vehicle inventory, and Army Guide documents HEAT projectiles for the AML-90's 90 mm F1 gun; this is a compatibility relationship, not proof that the projectile was fired in Yemen.

Documented 90 mm Designations
Public references use several labels for the French 90 mm HEAT family, so this page keeps the record broad while separating the best documented designation paths.
| Designation | What the source says | Context | Source |
|---|---|---|---|
| French projectile, 90-mm, HEAT-T, OCC 90 62 | Identified as a French 90 mm HEAT-T projectile with N.E.W. 670.00 g. | Direct public identification of the French 90 mm shaped-charge projectile. | JMU projectile guide |
| OCC 90-62 | Jane's records a 7.1 kg complete round, 3.6 kg projectile, 0.67 kg filling, 750 m/s muzzle velocity, and 320 mm RHA penetration at 0 degrees. | Earlier published reference for the French HEAT round in the wider 90 mm light-gun ammunition table. | Jane's AFV Retrofit Systems 1993-94 |
| OCC 90 F1 / OCC 90 F2 | Forecast International lists both as 90 mm high-explosive anti-tank tracer rounds under Nexter Munitions. | Related French HEAT-T designations exposed in the same source lane. | Forecast International Tank Gun Ammunition |
| 90mm F1 HEAT-T M630 | Nexter catalog lists it as a fixed HEAT-T round for current in-service CN 90 F1 (DEFA) guns. | In-service round in later Nexter/MECAR documentation. | Nexter 2016 catalog excerpt |
| 90mm F1 HEAT-TP-T M653 | Nexter catalog lists it as the matching training-practice round for the same gun family. | Ballistically paired practice round. | Nexter 2016 catalog excerpt |
Use Boundary
AML-90-family vehicles and turret conversions have documented conflict histories, but the consulted sources do not directly identify firing, transfer, or recovery of this exact 90 mm HEAT projectile in a named conflict.
