A CLGG works on the same principle as rocket engines: lighter propellant yields higher impulse. This type of system is has similar capabilities to a ram accelerator or conventional light-gas gun (>8km/s velocities achievable). It does face more significant engineering problems, but is easier to implement into CDE's existing module design framework. The oxygen version produces very large flashes, much like LOX-LH2 engines.
"Combustion light-gas gun technology is one of the areas being explored in an attempt to achieve higher velocities from artillery to gain greater range. [...] While this technology does appear to provide higher velocities, the main drawback with gaseous or liquid propellants for gun systems is the difficulty in getting uniform and predictable ignition and muzzle velocities. Variance with muzzle velocities affects precision in range, and the further a weapon shoots, the more significant these variances become. [...] The CLGG, like the railgun, is a possible candidate technology for greater ranges for naval systems, among others."

- Specific heats and thermal conductivities averaged from stock data on mixture constituents.
- Melting/boiling point from hydrogen as placeholder. I don't know how this would be handled for mixtures, although really the gases would be stored separately.
