The Tubes Do Not Move.
The Site Decides Everything Else.

CDNS Institutional is fixed-site protection against small uncrewed aircraft. It is one line and two products: the Pedestal Mount, a slewing, elevating head on a cabinet pedestal, and the Roof Mount, whose loads go into a building's primary structure rather than onto its deck. Both fire the rounds of the CDNS UAV Platforms line, and the sensing that cues them is built in-house.

The tube module is the one already drawn on the launch platform: Ø90.00 mm on the bore, 3.00 m of stroke, 30 bar of air behind it, and a normally closed solenoid breech on every barrel. A round is 1.600 kg and leaves at 189.2 m/s. Nothing on this line is a new round, and nothing on it is a new launch chain.

The line is not a remote weapon station and it has no automated fire mode. It carries no jammer, no spoofer and no other radio-frequency effect. There is no radio transmitter, no receiver and no satellite navigation receiver aboard either mount, every data path is wired or fibre, and neither mount carries an antenna. The console stands inside the site's secure area with a direct view of the mount and the sector it covers, and no workstation elsewhere on the network can arm or fire.

Loading is settled per site. A magazine feeds the breech from a locked store of rounds on an indexed carrier with no pyrotechnics in it; pre-loaded pods hold one ready round in each tube behind a locked, sensed cover, and are reloaded at the breech or by exchanging the pod. Either way the rounds are counted, the cover is a permissive, and nothing is loaded that the breech has not read.

A sensed stow lock pins the head at a stow attitude whenever the mount is SAFE and unattended, and the rangefinder is interlocked off while it is in. Every arm, fire and fault event is recorded with its time, its operator and its imagery, and the record cannot be edited in the field.

The round carries no chemistry, and that is not the hazard. The hazard is mass and speed: the design table gives 7.3 to 16.8 kJ at impact for a round that misses, and no lay in the envelope brings that below the bottom of the band. Sectors and elevation limits change where a miss comes down. They do not change how hard it comes down, and the case is written from that fact rather than around it.

Where a site controls the whole of the ground a round can reach, a surveyed footprint and a cam set cut to it carry the case. Where it does not, the design answer is a canopy carried in the round, and that work is engineering rather than a capability offered here.

The option is a packed canopy carried in the round's forward body bay, aft of the nose and head interface, on the airframe both heads share. The round keeps its 1.600 kg mass, its external envelope and its magazine pitch, and the launch case behind it does not change: 30 bar, 3.00 m of stroke and 189.2 m/s. The same option serves the kinetic head and the capture head.

What the engineering is working on is named rather than smoothed over. Every automatic release needs a lock driven by the launch itself and a condition that opens it, and that pairing is recognizable as the architecture of a safety-and-arming device — the company's distinction is that this mechanism opens a bay and initiates nothing, and counsel's opinion on it comes before any trigger is selected. The canopy's planform, its porosity, its packed volume against the bay, and whether a drogue stage precedes it are open engineering. No descent figure is published, and none will be until a built canopy has been deployed and measured.

Maintenance is a site's work too, and the schedule is short and fixed: the interlocks, the stop and the breech fail-closed proven at each use; harness and slew checks monthly; compressor service and breech seal inspection quarterly; the vessel hydrotest and the relief proof on the certificate. A lapsed vessel certificate takes the mount out of service. This line adds sensor window cleaning, dryer and desiccant service, a cam-set inspection and seal check, an anchor preload check, a foundation or roof-penetration inspection, a brake holding test, a tilt-switch check and a test of the uninterruptible supply.

The useful first conversation is about a place: what the ground is and who owns it, what stands within reach of it, whether there is three-phase power and somewhere to put a compressor and a bank, and who would hold the arm key. The sector cam set, the foundation, the pod and the loading all follow from those.

The two products are on the Pedestal Mount and the Roof Mount. The pneumatic chain both of them inherit is on the launch platform, the rounds on CDNS UAV Platforms, and the hazard register and interlock chain the line builds on are on safety on the launch line. What the company designs, owns and keeps control of is on sovereignty. Every enquiry is screened, supply is subject to Canadian government permits issued per shipment, and the reply comes in writing, from a person.
