There have been some updates to EMDAR that reflect new research data on EM dissipation. It turns out we have been over-estimating how much EM dissipates over distance, meaning EM emissions are easier to detect at lower output levels than previously thought. Which will make an EMDAR tech's life easier, but a quartermaster's life harder.

Previously only EM output above 60 SEMs were thought likely to be consistently detectable at ranges of over 3000GUs. Now, even EM output at 20 SEMs is consistently detectable (via extrapolation) at up to 7000GUs.

This is a first look at a firing solution calculator prototype. This will be used to calculate the ideal combination of range and speed for a torpedo launch in order to hit its target (a “prosecution”).

This is a proposed firing solution for torpedos for our MVP. Being an MVP it is a much more simplified version that what the final will be. The primary aim of the MVP is for us to see how it performs in the hunter killer simulations and gather data on user interaction with the system. A lot of the numbers of the system have not been decided left and will be left out of this while they are tweaked. This post is less about the math and more about the method.

For now firing is design to happen at Impulse speed.

Firing can be split in to 4 phases:

The launch system planned for torpedoes is railgun based, which relies on a magnetic field to amplify initial velocity from an explosive launch. This should give us launch velocities of at least 10K km/sec, depending on the length of the railgun.
