frigate, really needs a name
SA frigates are named after major battles in human history, and the class is named after the first ship of that class. So for the Roman theme pick a historical Roman battle.
Or if we want to play a little politically there was just a battle at Mindoir, so we could call it the Mindoir class.
2) TIR has unlimited stamina - due to the inner layer the heat gets trapped outside the ship, not inside of it. Normandy's stealth has limited active time. In principle TIR offers unlimited active time. Static discharge is a problem, but that, I think, takes weeks.
FTL grade ME fields have about three day of endurance with current core sizes. Endurance is relative to both the amount of eezo and possibly (wiki doesn't say this but it does make sense) the amount of power run though the eezo. The Normandy for example has a double strength core and can run twice as long as other ships. A TIR system would either require using the FTL core and thus not being able to use FTL (or vice versa) or adding even more expensive eezo. I doubt we're going to get "weeks" of endurance w/o making far to expensive ships. No clue how much eezo is needed as we'd need the index of refraction for ME fields (black magic as noted below) and a working copy of the eezo equation which all we know has power and eezo requirements that are exponentially dependent on the mass effected and the amount its effected by (possibly meaning that a FTL field in a vacuum is actually quite easy) though that might be a rule of thumb equasion.
Hell part of me wounder if part of the Normandy's ability to trap all that heat isn't due to using mass effect fields to catch some of that heat, its never explained how it works exactly other then that the heat is stored in Lithium sinks and the stealth system is "powered by" the Tantalus drive core.
Its also important to note that TIR is dependent on the angle of the incoming light. TIR will
NEVER occur (barring space magic) when the light waves hit perfectly perpendicular to the boundary between the mediums (that is the angle to the normal is 0, and perpendicular to the boundary) this is due to the formula for the "critical angle" for TIR being theta=arcsin(n
2/n
1) with n
1 being the index of refraction for material the light starts in and n
2 being the material the light (might be) traveling into. Index of refraction is n=c/v, where c is the speed of light and v is the speed of light in the material. So simplified its arcsin(v
1/v
2), with v
1 being the speed of light for of the material the lights in and v
2 being the velocity of the material the light is passing into. To minimize the value for theta one needs a value of 0 for v
1 or a value of infinity for v
2, which would mean stopped light or infinity fast light. For ME this would be singularity class effects or Mass Relay class fields. Surrounding the ship in a singularity is not going to be good or its health and Relay level fields are out side our grasp (for now).
Wiki for TIR:

Random physics question: why the hell do they include C in these equations? It drops out so it shouldn't matter... is it just because they use the index of refraction as a baseline and that uses C? Though in ME it may matter due to the direct manipulation of C... ME Wiki claims otherwise though.
In conclusion total stealth via TIR isn't happening it may help and a well structured field may produce a (very) low emissions level of stealth; placing the primary radiators so that the radiated heat will not strike the TIR barrier perpendicularly, should reduce the emissions a massive amount, but no magical cloaking. TIR will how ever offer a good way to reduce the effects of lasers a thin layer of FTL grade ME field (rated at 57x C) will block all lasers not hitting exactly within 1 degree of the normal, which is some thing like a 98% drop in efficiency. It also produces a very narrow window to detect you in. The reapers do have
anti-laser shielding already you know, mind its not perfect.

TIR would also make it hard to run a normal shield though being that hard to see may make it meaningless.
Unless I missed something...
