Notes: The most successful design of vessel in Klingon
history, the B'Rel class has been in service in larger numbers
and subtypes for a longer than any other class in known space.
First fielded in the 2260's, the B'Rel was built from the start to
fill a variety of roles. As a special operations ship she would using
her cloak to penetrate the Federation border and attack lightly
defended targets such as sensor outposts, communications relays and
cargo craft, creating confusion in advance of a Klingon fleet attack.
She is also a natural scout ship, ideal for locating and tracking
Federation and Romulan fleets from under cloak. During the long period
of tensions between the Federation and Klingon Empire, many B'Rel
class vessels operated as Raiders, cruising deep inside Federation
space to pick off occasional lone vessels or outposts.
Although the B'Rel was a potent
threat to the Federation in this role, one such vessel was captured by
Admiral Kirk in 2285. Admiral Kirk was at this time operating without
Starfleet authority. The ship later sank in San Francisco Bay during
an attempted landing. The ship was raised from the water and studied.
This provided crucial information in devising countermeasures for use
against the B'Rel. It aided in Starfleet's efforts to modify sensor
networks already in operation on its ships and installations in order
to increase their effectiveness. Despite this, these vessels have
remained a factor to be reckoned with ever since. Many hundreds
continue in service today, having been vastly upgraded over the years.
In design the B'Rel conforms to
Klingon norms, with a single torpedo tube at the extreme forward point
of the hull. The bridge is above this, with crew quarters located in
the neck section. The rear of the ship comprises the engineering
compartments and a small cargo bay. A pair of wings carry disrupter
cannon at their tips, while a single fire emergency torpedo tube
provides a backup to the main armament. The wings allow the B'Rel to
operate in an atmosphere and landing gear is fitted.
