Projectile OE 155 56/69
155 mm OE 155 56/69 - a high-explosive fragmentation projectile from a French manufacturer Nexter Systems. This type of projectile has a forged steel body with a flat boat-shaped base and a long streamlined ogive, which ensures its stability in flight.
The projectile is painted gray-olive with yellow markings, where yellow indicates the hexogen-TNT filler, also known as hexolite or an RDX/TNT mixture. This explosive composition provides a powerful blast effect on impact.
The projectile body is surrounded by a copper driving band, which ensures the projectile's rotation and stabilization in flight. The band is usually covered by a sleeve until loading into the gun. The nose cavity is threaded, which allows various types of fuzes to be installed depending on the combat task, and is initially closed with a lifting plug for safe storage and transport.

Usage notes
The main 155 mm howitzers in NATO are the M114, FH70 and M109 series. France is an exception. All NATO howitzers, including French ones, use American M107 HE-type ammunition. French OE 155 56/69 (HE)-type ammunition can be used in American howitzers, but this requires separate firing tables.
Used with fuzes: M557, M564, M500, M51A4, M51A5, M520, M520A1, PD M51 A5, FU RALEC (F1, F2 and F3).
Tabular changes of projectile weight:
██ ██ - 42.75 kg
██ ██ ██ - 43.25 kg
██ ██ ██ ██ - 43.75 kg
██ ██ ██ ██ ██ - 44.25 kg
██ ██ ██ ██ ██ ██ - 44.75 kg
Usually supplied with its own propellant charge CN 155 AU F1. This charge is present in Kropyva for the TR F gun, but for the OE 155 56/69 (HE) projectile there is data only with this charge CN 155 AU F1. The OE 155 56/69 projectile, which is used with the propellant charge CN 155 AU F1 to the charge M232A1 can conditionally be compared as follows:
- - CN 155 AU F1 charge 5 (19 km) - M232A1 charge 4 (18.5 km)
- - CN 155 AU F1 charge 4 (15.4 km) - M232A1 charge 3 (15.1 km)
But the flight of the French OE 155 56/69 (HE) projectile does not correlate with other NATO munitions and you will not be able to determine the flight trend from Kropyva. Your own experience is needed.
