LoL I just did a write up yesterday of the Lantean Aurora-class Battleship equipped with Drone missile launchers (and will post most likely today) and built the launcher close to how you have done.
The big thing with Drones is they can penetrate almost anything (most shields, hull armour and vessels themselves), plus they do not automatically explode upon impact with he ship, they are described as burrowing through a vessel, doing collateral damage along the way and then targeting a power source, travelling to there and then exploding. Very difficult to replicate in Space Dock (basically a plot weapon)
"Drone weapons, known more colloquially as drones, are projectile weapons that serve as the primary weapon system of the Ancients. A hybrid energy/projectile weapon, drones are capable of penetrating most shields and armor with ease. A single drone can destroy most fighters and cause severe damage to smaller capital ships, while hundreds or thousands can obliterate dozens of vessels with little effort."
"When active, a drone emits an energy field capable of burning through nearly all forms of conventional matter, as well as allowing it to punch through energy shielding with ease. This not only renders a drone capable of causing severe damage in a single strike, but allows it to make multiple attack runs on a single target before running out of energy. Drones are precision weapons, designed to cause massive damage to small targets without destroying anything around them. This makes them ideal as anti-fighter or anti-ship weapons, but less effective as ground-suppression weapons, despite their low collateral damage."
"Drones are among the most powerful weapons in existence. They can pass through Goa'uld shields with ease and punch through the organic armor of Wraith Hive ships without being destroyed. In an alternate reality, it was stated that an Ori warship was driven off by drone weapons, though it's not made clear if it simply retreated or was destroyed. Two or three drones are sufficient to destroy a Ha'tak vessel or an Asuran Aurora-class battleship when the ships are hit in key areas, which drones automatically detect and aim for, and a few dozen drones tore apart a Hive ship in less than a minute. Asuran Aurora-class battleships have drones as well, but since the Asurans stopped technologically at the level the Ancients were at when the Asurans were created, which was in the height of the Wraith-Ancient war, it seems likely that the Ancients had more advanced drones."

Wave Man, the term "wave man" is the English translation of 'Ronin' (Japanese word) and literately translates to "wandering person" and in a modern context a WaveMan is one who is socially adrift or a SalaryMan who is between employers.
