Reverse engineering the covenants weakest ship-to-ship weapon really isn't that far fetched. Not only did it take them like, 20 years minimum to do it. But in real life, we can allready use lasers.
The pulse laser is their weakest? Aren't the plasma torps? I mean apparently a Halcyon can only resist 1-2 lasers, where at the end of the first level of halo we saw the Autumn taking like 8 torps.
And at the end of Cairo station (halo 2)we saw a Marathon get badly damaged/destroyed by a pulse laser (granted it could have been hit by 50 before that-we didn't see.)
Are pulse lasers a standard size or do different ships have different sized projectors? Or maybe there are different variants (like MACs)
Now shields, we have NO idea how we could make a shield, and they didn't in Halo either.
Who says you need to have an idea? Imitate?
They also never got any sort of covenant shield tech to aid them (Talking about ships here, not infantry.) So that made it all the more difficult.
Well for all we know they scaled it up from infantry big time or they got it some other way. We have to face that there are some gaps in the story like with the pulse laser, just go with what we know (and that is that the Hood class was getting sheilds)
We don't know how powerful they were ect.
I am pro shields (not voted though)but weak and a very high level of research and not on all vessels, as well as being slow regeneration.
And if it took them 20 years to reverse engineer the weakest component the Covenant had on their ships, how long do you suppose it'd take to reverse engineer the strongest one they had?
Stronger =/= more advanced- look at MACs, they are fairly simple, yet they own archers which are more advanced (they need propellants, guidance, sensors ect)
