The 80 ft Nasty PTF-7 is a rank I American motor gunboat with a battle rating of 1.7 (AB/RB/SB). It was introduced in Update 1.79 "Project X" as part of the fleet closed beta test.

General info

Survivability and armour

This boat's only armour is located at the 2 x 20 mm turrets. It consists of two 12.7 mm plates sloped at 8 degrees. Ammunition for these guns are located below the waterline and forward of the bridge. The rear of the contains the boat's two engines.


Fully upgraded the boat has decent turning capabilities. Its speed when fully upgraded matches that of similar class torpedo boats.

Primary armament

The 2 x 20 mm Oerlikon Mk.II cannons are located on either side of the bridge. They provide a cone of overlapping fire of approx 45 degrees to the front and rear of the boat. Ammunition is available in Universal, HE, and AP.

The single 12.7 mm AN-M2 machine gun is located in front of the bridge. The location does mean that it has a blind spot to the rear of the boat. Ammunition is only available in the default load.

Secondary armament

The 40 mm cannon is located mid-ship facing aft. This provides it with an excellent field of fire to the rear but means a blind spot to the front of the boat. Ammunition is available in Universal, HE, and AP.

Special armament

Main article: Mk 2 (81 mm)

The 81 mm mortar is available once researched and fires HE ammunition. Once installed, the mortar will take the place of the 12.7 mm machine gun on the front gun emplacement.

Usage in battles

Describe the technique of using this ship, the characteristics of her use in a team and tips on strategy. Abstain from writing an entire guide – don’t get try to provide a single point of view, but give the reader food for thought. Talk about the most dangerous opponents for this vehicle and provide recommendations on fighting them. If necessary, note the specifics of playing with this vehicle in various modes (AB, RB, SB).

Pros and cons


  • High speed, giving the ability to re-position and engage targets at will
  • Effective 20 mm Oerlikon cannons against other small craft
  • Highly destructive 40 mm Bofors against small craft, and serve against larger vessels
  • Combined Bofors and Oerlikon cannons provide an effective anti-aircraft armament


  • Lack of torpedo armament makes attacks against larger vessels exceedingly dangerous
  • Large size makes it an easy target, and lack of any hull armour means low survivability
  • Inability to use all armaments at once, due to 40 mm Bofors being located on the aft end of the ship
  • Lengthy reload time for the 20 mm Oerlikons can be detrimental in the middle of a fight


The Nasty-class of patrol boats was originally the work of a private venture in Norway as an attempt to build the best possible patrol craft featuring all of the best attributes of those from World War II. The first prototype was built in 1957 for the Royal Norwegian Navy and tests were shown to be successful.[1] The Nasty used a sleek wooden hull combined with two Napier Deltic engines, each providing 3,100 HP, for a speed of over 74 km/h (40 knots). It was designed to accommodate a range of weaponry for any role.

With the escalation of the war in Vietnam, the United States saw a need for new patrol boats as nearly all of the ones from World War II had been scrapped or were unusable. Several countries made contracts with the Westermoen shipyard in Norway to construct Nasty-class patrol boats and the United States purchased 14 of them which were delivered in 1964. An agreement was also made for six to be built under license at a shipyard in Annapolis, with those being delivered in 1967.[2] These were all put into service as they were acquired, being employed in South Vietnam and designated Fast Patrol Craft (PTF). A few of the Nasty-class boats (PTF-7 included) were used to train South Vietnamese Navy crews and given to them for a period of four years but were all returned to American service in 1970. During the war, the Nasty PTFs were used for shore bombardment and secret mission by special forces units along the coast. Out of the 20 total built, 6 were lost in action. After the end of the war, the Nasty boats were used sparingly, as the maintenance costs were high and they were all eventually decommissioned by the end of the 1970s with many were scrapped. A small few likely remain in existence, although many are merely hulks which have been stripped of all equipment and are in poor condition.


An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
