The '''TRF1''', originally known as '''GIAT 155 mm Tracté''' (TR) is a [[155mm]] French towed [[howitzer]] produced by [[Nexter]] (ex Giat Industries) and used by the [[French Army]].

The TRF1 was showcased in 1979 at the Eurosatory arms trade show, as a replacement for Armée de Terre's [[Obusier_de_155_mm_Mod%C3%A8le_50|BF-50]]. Giat produced it from 1984 to 1993.

==Performance==
*Setting out of battery: 2 min
*Crossing of slopes of 60%, fords of 1.20m.
*Horizontal field of fire: 445mil to the left, 675mil to the right.
*Hydraulic [https://www.defense.gouv.fr/actualites/ukraine-france-dresse-bilan-equipements-militaires-livres aiming]

==Ammunition==
*Capacity of tractor: 56 rounds, 32 on pallets and 24 in racks.
*Can fire all 155 mm ammunition (the normal ammunition is the [[high-explosive shell]]).
*Casings are combustible, which improves rate of fire: there is nothing to extract before reloading.

==Combat history==
The TRF1 was used in combat by [[Ukrainian Ground Forces]] during the [[2022 invasion of Ukraine]]. Photographic evidence shows that at least one TRF1 was destroyed in combat near [[Lyman, Ukraine|Lyman]].<ref>{{Cite web|url=https://www.oryxspioenkop.com/2022/02/attack-on-europe-documenting-ukrainian.html|title=Documenting Ukrainian Equipment Losses During The Russian Invasion Of Ukraine}}</ref>
