Modern navies began a trend in the late 20th and early 21st centuries of building corvettes geared towards smaller more manoeuvrable surface capability. These corvettes have displacements between and measure in length. They are usually armed with medium- and small-calibre guns, surface-to-surface missiles, surface-to-air missiles (SAM), and anti-submarine weapons. Many can accommodate a small or medium anti-submarine warfare helicopter, with the larger ones also having a hangar. While the size and capabilities of the largest corvettes overlap with smaller frigates, corvettes are designed primarily for littoral deployment while frigates are ocean-going vessels by virtue of their greater endurance and seaworthiness.
