The nominal diameter of a projectile. For most modern munitions, this is expressed in millimetres (e.g. 82 mm mortar projectile), but older artillery gun projectiles may be described in inches.
Munitions that are delivered from above the surface of the earth, typically from an aerial vehicle, and designed to strike other aerial targets, including aeroplanes and UAVs.
This image shows a Hydra-70 rocket fitted with an Advanced Precision Kill Weapon System (APKWS) guidance kit, converting it into a guided missile. In this case, the missile features an M151 high explosive (HE) warhead fitted with either an M427 or M423 point-detonating (PD) fuze. The rocket motor model cannot be determined from this source alone, but it is most likely to be a MK 66-series motor. The launcher appears to be a LAND-LGR4 model produced by Arnold Defense. (ARES)
This image represents the first documented instance of a Shahed-series UAV carrying an R-60 air-to-air missile. This appears to add a new capability to the Shahed, enabling it to target enemy aircraft. Arming UAVs to counter interception and engage alternative targets is an emergent trend. Previously, unmanned surface vessels (USVs) employed by the Ukrainian Armed Forces have been observed carrying R-73 air-to-air missiles, for example. (ARES)
This image shows the rocket motor of an AGM-114 "Hellfire" series guided missile found in Jordan during the 12 day conflict between Israel and Iran. This specific Hellfire missile is likely an air-to-air "C-UAS" variant used to intercept one-way attack drones, such as those launched by Iran towards Israel, rather than the more common air-to-surface Hellfire missile variants.

Two R-77 air-to-air missiles (NATO reporting name: AA-12 Adder) are carried in this photograph by a Russian Aerospace Forces Sukhoi Su-35 fighter aircraft. Key markings, including the aircraft’s bort number (a coloured numeral that acts as a unit or base identifier), have been digitally obscured. (ARES)
This F-16I fighter aircraft from the Israeli Air Force is carrying a CATM-120 inert missile simulant (indicated). These devices are used for training purposes, being designed to replicate the weight and centre of gravity of a live munition. They lack any means of propulsion and are not released from the aircraft. The CATM-120 can be differentiated from the AIM-120 missile series by the presence of only blue bands on the missile, denoting both an inert rocket motor and an inert payload. A ‘live’ AIM-120 will have two brown bands on the rear section of the missile (the rocket motor), and a yellow band on the forward, or warhead, section. An AIM-120 with an inert warhead, but a live rocket motor, will have a blue band on the warhead and two brown bands on the rocket motor. (ARES)
