One of the most fearsome weapons on land is present on the Project 771 landing ship of the Vietnam People's Navy.

Although Vietnam received aid from the Soviet Union for these ships, they were built at the Stocznia Polnocna factory in Gdynia (Poland). Photo source: QĐND newspaper |

| The Polnocny-B Project 771 landing ship has a full load displacement of 834 tons, length of 73m, width of 9.6m, draft of 2.3m. The ship is equipped with two 4,400 horsepower diesel engines for a maximum speed of 33km/h, range of 2,000km. Photo source: Vietnam Defense Channel |

| According to published Russian technical documents, the 771 class of amphibious transport ships is capable of carrying up to 5 T-54/55 or PT-76 tanks or BTR-60 armored vehicles; or 3 towed guns or 122mm, 152mm; or 3 ATS-1 towed guns; or 9 Zil-151 trucks or 19 GAZ-69 jeeps.

| In general, the amphibious transport features of Project 771 are not special or too large, they are only considered light - medium landing ships. However, the firepower of 771 is really formidable, it must be affirmed that the enemy will definitely be "terrified" when the 771's weapons spray fire to support the marines - tanks to retake the island and coast.

| Accordingly, on the deck of each Project 771 warship are equipped with two WM-18 Ogon 18-barrel 140mm rocket launchers. This type of gun is related to the famous Grad multiple rocket launcher on land, a weapon that always makes the enemy terrified when it screams. Photo source: Vietnam Defense Channel |

| The WM-18's firing range is up to 9,800m, or at least 1,000m, allowing effective support for landing forces at close range or deep inland. Photo source: Vietnam Defense Channel |

| Meanwhile, the largest landing ships of the Vietnam People's Navy - Ship 501, were built using World War II technology - these ships were spoils of war after 1945 - so it is not surprising that their firepower is weaker than that of the 771 despite their much larger size. Ship 501 is about 100m long, with a full load displacement of up to 4,000 tons. Photo source: Navy Television |

| However, the firepower of the 501 ship is only the 40mm Bofors twin-barrel gun mounts with a range of about 7.1km. Photo source: Navy Television |
