Kaliber 30 mm

Kaliber 30 mm adalah ukuran tertentu dari amunisi senapan maupun meriam. Amunisi tersebut termasuk peluru standar NATO 30×113mmB, 30×173mm (STANAG 4624), dan 35x228mm NATO, 30 × 165mm Soviet, 30x210mmB, dan 37×250mm, Yugoslavia 30x192mm, dan Cekoslowakia 30x210mmCz yang banyak digunakan di seluruh dunia.
Amunisi 30 mm biasanya tidak digunakan untuk melawan personel, melainkan sebagai peluru antimateri atau peluru penusuk lapis baja. Butiran peluru sebesar ini bisa efektif melawan kendaraan lapis baja ringan serta bunker yang diperkuat. 30mm juga merupakan kaliber yang populer untuk sistem senjata kapal jarak dekat, seperti AK-630 Rusia dan CIWS Kiper Belanda.
Angkatan Bersenjata Federasi Rusia menggunakan senjata 30 mm mereka dalam berbagai kendaraan, termasuk pesawat tempur Su-25, helikopter Mi-24, helikopter serang Mi-28, helikopter serang Ka-50, dan BMP-2, BMP-3, dan kendaraan tempur infanteri BTR-90. Sistem meriam antipesawat paling modern yang digunakan oleh Rusia adalah 30 mm. Militer AS menggunakan senjata 30 mm di A-10 Thunderbolt II dan helikopter AH-64 Apache mereka.
Amunisi 30 mm umumnya tersedia dalam tiga jenis: armor-piercing (AP), high-explosive (HE), dan butiran training. Peluru penusuk lapis baja dan bahan peledak tinggi biasanya juga memiliki karakteristik pembakar.
