155 mm (6,1 in) adalah kaliberpeluru artileri standar NATO yang digunakan di banyak meriam lapangan, howitzer, dan gun-howitzer. Hal ini didefinisikan dalam AOP-29 bagian 1 dengan mengacu pada STANAG 4425.
Perang darat
Kaliber 155 mm berasal dari Perancis setelah dikalahkan dalam Perang Perancis-Prusia (1870–1871). Komite artileri Prancis bertemu pada tanggal 2 Februari 1874 untuk membahas model baru artileri benteng dan pengepungan Prancis, di antaranya terdapat senjata dengan rentang kaliber 14–16 cm (5,5–6,3 inci) (yang kemudian dikenal sebagai De Bange 155 mm meriam). Setelah beberapa kali rapat, pada tanggal 16 April 1874 panitia menetapkan kaliber 155 mm (dalam surat program panitia berikutnya tertanggal 21 April 1874, kaliber untuk pertama kalinya dinyatakan sebagai 155 mm).
Sejak awal abad ke-21, sebagian besar tentara NATO telah mengadopsi senjata 155 mm sebagai standar serba guna. Mereka dipandang sebagai kompromi yang baik antara jangkauan dan kekuatan, sementara hanya menggunakan satu kaliber saja akan sangat menyederhanakan beban logistik. Hal ini menyebabkan keusangan artileri kaliber lebih besar seperti 175 mm (6,9 in) dan 203 mm (8,0 in). Beberapa pihak militer tetap mempertahankan senjata kecil kaliber 105 mm (4,1 in) karena bobotnya yang ringan dan mudah dibawa. Rusia dan negara-negara bekas Blok Timur cenderung menggunakan artileri 122 mm (4,8 in), 130 mm (5,1 in) dan 152 mm (6,0 in) dalam peran yang sama.
Peperangan laut
Sejak akhir Perang Dunia II, kaliber 155 mm belum digunakan oleh angkatan laut meskipun sudah ada di mana-mana di darat dengan sebagian besar angkatan laut NATO dan sekutunya menggunakan kaliber 76 mm (3,0 in), 100 mm (3,9 in), 114 mm (4,5 in). in), atau senjata 127 mm (5,0 in) di kapal perang modern. Pada satu titik, Kementerian Pertahanan Inggris mempelajari "up-gunning" senjata angkatan laut Mark 8 4,5 inci milik Angkatan Laut Kerajaan untuk memberikan peningkatan daya tembak dan kaliber yang sama antara Angkatan Laut Kerajaan dan Angkatan Darat Inggris. Meskipun secara dangkal tampak lebih rendah berdasarkan perbandingan sederhana diameter peluru, ketika menembakkan amunisi konvensional, meriam angkatan laut Mark 8 4,5 inci yang lebih kecil sebanding dengan meriam howitzer standar 155 mm milik Angkatan Darat Inggris. Cangkang standar dari meriam angkatan laut Mark 8 4,5 inci memiliki jangkauan yang sama, jika tidak lebih baik. Hanya dengan menggunakan proyektil berbantuan roket (RAP) sebagian besar meriam 155 mm dapat memiliki jangkauan yang sebanding dengan meriam angkatan laut Mark 8 4,5 inci dan dengan demikian terjadi pengurangan muatan. Hal ini karena senjata angkatan laut dapat dibuat jauh lebih kuat daripada senjata self-propelled gun-howitzer di darat, dan memiliki laras yang lebih panjang dibandingkan kalibernya (misalnya meriam angkatan laut Mark 8 4,5 inci memiliki panjang laras 55 kaliber, sedangkan senjata self-propelled standar AS-90 memiliki panjang laras 39 kaliber). Hal ini memungkinkan senjata angkatan laut menembakkan peluru yang lebih berat dibandingkan dengan diameter peluru dan menggunakan bahan bakar yang lebih besar dibandingkan dengan berat peluru, sehingga menghasilkan kecepatan proyektil yang lebih besar. Bahkan tanpa pendinginan aktif, laras senjata angkatan laut yang lebih berat memungkinkan laju tembakan berkelanjutan yang lebih cepat dibandingkan senjata lapangan, dan hal ini dimanfaatkan dengan sistem pemuatan otomatis dengan kapasitas beberapa ratus peluru. Meriam 155 mm lebih baik daripada meriam angkatan laut Mark 8 4,5 inci dalam menembakkan proyektil terpandu yang diluncurkan meriam (CLGP) karena kecepatan peluru 155 mm yang lebih rendah membuatnya lebih mudah bagi sistem panduan elektronik internal proyektil untuk bertahan saat ditembakkan.
Meskipun Advanced Gun System (AGS) Angkatan Laut AS juga menggunakan kaliber 155 mm, namun tidak kompatibel dengan amunisi 155 mm standar NATO. Hanya satu jenis amunisi yang pernah dikembangkan dan pengadaannya dihentikan pada tahun 2016 karena biayanya yang tinggi, sehingga AGS tidak dapat digunakan.[1]

The M395 projectile carries 63 bomblets to a maximum range of 224 km (139 mi); the extended range M396 and M397 projectiles both carry only 49 bomblets and have a base bleed unit to a maximum range of 287 km (178 mi) and 30 km (19 mi) respectively.[3]

A series of laser-guided projectiles primarily produced in the Eastern Bloc standard 152 mm (6 in) caliber, they are also produced in 155 mm caliber for the export market. First fielded by the Soviet Army in 1987, they are regarded as the Eastern Bloc equivalent of the US M712 Copperhead. The 152 mm versions have a maximum range of 20 km (12 mi) from the D-20 gun-howitzer and 22 km (14 mi) from the longer-barrelled 2A65 Msta-B. They are licence produced in China by Norinco.[4]

Maximum range of 117 km (73 mi). Developed from 2000 and tested in the 2010s it was cancelled in 2016 due to excessive cost of projectiles.[12]
Standard HE projectile developed from the M102 for use in the 155 mm Howitzer M1. The projectile is one of the most widely used of all western artillery projectiles and is fired from a variety of 155 mm towed and self‐propelled howitzers. Largely replaced in US service by the M795.[13]
M483A1 Dual‐Purpose Improved Conventional Munitions (DPICM) projectile is a dual-purpose anti-armour/anti-personnel projectile that consists of a carrier shell and 88 individual grenade submunitions. Introduced in 1975, it is used by a number of nations. From 2009 the US have been decommissioning their stockpile of rounds, reusing the bodies to make smoke, illumination and training projectiles.[14]
The M549 and M549A1 High-Explosive Rocket Assisted (HERA) shells are rocket-assisted projectiles designed to provide extended range over conventional shells. Maximum range of 301 km (187 mi) from a NATO-standard 39‐calibre howitzer. The M549A1 is one of two projectiles for which the M1156 PGK fuze has been developed.[15]
The M692 and M731 Area Denial Artillery Munition (ADAM) are anti-personnel mine scattering projectiles. They share the carrier shell of the M483A1 DPICM and instead carry 36 anti‐personnel mines. They are no longer produced or in service although it is assessed the US maintains stockpiles.[16]
A laser-guidedHEAT projectile. Developed in the 1970s and early 1980s, it saw service with the United States and several allies from the mid-1980s. Production ceased in 1990 and as of 2015 only residual stocks remain. Maximum range was 16 km (9,9 mi) from a 39‐calibre howitzer.[17]
The M718 and M741 Remote Anti-Armor Mine System (RAAMS) are anti-tank mine scattering projectiles. They share the carrier shell of the M483A1 DPICM and instead carry 9 anti‐tank mines. They are no longer produced or in service although it is assessed the US maintains stockpiles.[16]
General purpose HE projectile developed with the intention of supplementing and eventually replacing the M107 in the US war stocks. Maximum range 24 km (15 mi) from a 39‐calibre howitzer. The M795 is one of two projectiles for which the M1156 PGK fuze has been developed.[18]
