Phaser systems:

Fortuna firing its phasers

The Fortuna utilizes the Type-10 phaser  array system. The dorsal saucer section is covered by four phaser arrays, two of which extend from the aft curvature, along the length of the saucer and stop short of the auxiliary deflector incision. The aft firing arc is covered by two smaller arrays, angled on the rear of the saucer section. The relative bottom of the ship is protected by two similar arrays as on the dorsal saucer section, extending to the rear of the saucer and following the curve to the auxiliary deflector incision.
 
More protection is provided by an array that extends across the ventral engineering hull just fore of the warp core ejection port. Far-aft strips are provided on the underside of the mobile nacelle pylons and under the shuttle-bay landing deck on the underside of the ship for a total ship's complement of 13 arrays.

Torpedo systems

The Fortuna houses five standard torpedo launchers (two fore, two aft, and one on the base of the engineering hull ), loaded with Type 6 Mark XXV photon torpedoes,  capable of pattern firing as well as independent launch. The Fortuna can carry a maximum of 55 torpedo casings.

Deflector shields

The Fortuna’s deflector shields react under incoming fire

The Fortuna’s deflector shield is a symmetrical, oscillating subspace graviton field. During combat, the shield sends data on what type of weapon is being used on it and what frequency and phase the weapon uses. Once the tactical officer analyzes these data, the shield can be configured to have the same frequency as the incoming weapon but different nutation. This tactic dramatically increases shield efficiency. There are a total of 14 shield grids on the Fortuna.
