The Perth class dispenses with the largest mass drivers in favour of an enormous Viper super-heavy anti-ship laser, one of the largest weapons ever to be mounted to a UCM vessel. This colossal weapon takes up over half the ship’s length. It is devastating if unsubtle when fired and fully capable of neatly slicing a cruiser in two. The Viper’s obvious energy signature necessitates use by a skilled captain if enemy retribution is to be eluded. The massive generators and power storage facilities needed to feed this beast of a weapon precludes the launch bays featured in the Johannesburg, although the Perth compensates by doubling the UF-4200 mass driver armament of its sister class.
At this point we were on the fourth version of the internal damping, where we focused our energies on reducing the backwave as much as possible (for maximum midrange punch and treble clarity) without killing the port resonance (keeping the lows as big as possible). That approach was quite unique but very effective. We were on Bracing and Damping from mid 2010 to early 2012. And then on Bracing and Damping thanks to the CNC machine - the damping is now raised away from the main panels in many spots which improves its ability to attenuate midrange bounce by acting on a higher velocity lower pressure part of the wave (as in TL designs).
