Fleet Avenger Battle Cruiser
The Fleet Avenger Battle Cruiser is a Vice Admiral level (Tier 5) Federation Battle Cruiser, the first of its kind. As the name suggests, the Avenger shares many characteristics with Klingon Battle Cruisers, having been designed for war and not exploration. Players can obtain the vessel through any Shipyard for 20,000 and 4 , as long as the player's Fleet has a Tier IV Fleet shipyard. It can be purchased for only 20,000 and 1 if the Avenger Battle Cruiser has already been purchased from the C-Store.
 Avenger class
The outboard warp nacelles are rectangular blocks, with optional fins for atmospheric stability. The pylons curve upward, though the Fleet Avenger can use a pair of straight, wing-like pylons that place the nacelles parallel to the secondary hull. The deflector dish is heavily armored, and only exposes a small "lit" portion, unlike the open dishes of other vessels.
The Avenger sports few windows, and those that are present are recessed into armored grooves that automatically seal up in combat. Windows along the secondary hull and neck are set on the inner surface of the hull to protect them from enemy fire.
The Fleet Avenger Battle Cruiser improves on one of the standard Avenger Battle Cruiser's only weaknesses - its durability. With the Fleet upgrade providing the ship with extra Hull and Shield strength over the standard Avenger, as well as a better shield modifier, the Fleet Avenger is better suited to withstanding punishment. With 5 fore weapons slots, 4 Tactical and Engineering consoles, the ability to mount Dual Cannons and a superior Turn Rate (9), the Fleet Avenger offers a great mix of hitting power and survivability.
The ship's main weaknesses are its lack of Science abilities (despite the addition of an extra console) and only 3 aft weapons slots, leaving the ship vulnerable to Alpha-Strike tactics, especially by decloaking Klingon and Romulan ships. To counter this, it is highly recommended that the player equip the Cloak from the Dreadnought Cruiser or the Tactical Escort Retrofit if they have it, granting the ship a strong Alpha-Strike capability of its own.
