The South African Denel-Mechem NTW-20 is a 20mm anti-material rifle and arguably the world’s most powerful sniper rifle. Its 20mm cartridge is 50% larger than the .50 caliber and has an effective range of over 3,000 yards.

The NTW-20 is a South African anti-materiel rifle or large-calibre sniper rifle, developed by Denel’s Mechem division in the 1990s. The weapon was designed by Tony Neophytou and intended for deployment against a wide variety of targets, including parked aircraft, telecommunication masts, power lines, missile sites, radar installations, refineries, satellite dishes, gun emplacements, bunkers and personnel, using a range of specialized projectiles. The NTW-20 in 20 x 110 calibre is a new version of the weapon. The accurate high explosive capability makes it extremely effective in the counter-sniping role, where indiscriminate fire from weapons such as mortars and rocket launchers is completely unacceptable. The new NTW 20 are now offered in 20 x 110 mm Hispano calibre. This calibre is highly efficient in terms of velocity, penetration and target effect.

Pictured here with its autocannon.
12-cylinder V-type, 930 horsepower

It gave the D.520 a top speed of 540km/h and a range of 1540km

Empty weight of 2092 and 2790 when loaded.
Less than 900 produced.

Arguably the best French fighter of the World War 2, similar in many aspects to the earlier Messerschmitt Bf109, with a better autonomy, maneuverability and ease of maintenance but failing to attain anywhere near its production run before the fall of France.
