The debate on why the UNSC didnโt implement energy shields on its naval vessels during the prolonged conflict with the Covenant continues to spark intense discussion. As experts weigh in, fresh insights appear to shed light on the situation from the forum community.

For almost three decades, the UNSC battled fiercely against the Covenant, facing significant resource limitations. One participant articulated that โthe UNSC had been working on advanced technologies for a while, but the war consumed much of the resources needed for R&D.โ Despite this, they managed to roll out energy shields on select ships post-war, like the UNSC Infinity and the Pillar of Autumn class cruisers. This illustrates a delayed but eventual shift in naval strategy toward better protection.
Financial and manufacturing constraints notably hampered the implementation of energy shields. One commentator explained, โOutfitting the navy would mean revamping your entire industrial complex, which is not a smart idea during a war.โ Furthermore, the technology to adapt energy shielding for ships was still evolving. As one user put it, โIt took them 26 years to fully develop warship-scale shields.โ Initial tests showed that existing ship designs lacked the power needed for sustaining shields, and upgrades would have been necessary.
The UNSC Antaeus demonstrated early ambitions to integrate reverse-engineered shielding technology with upgraded capabilities, which started to take shape only after the Covenant War ended. According to a source, โDespite obtaining technology from captured ships, production delays hindered the quantity needed.โ As a result, many ship classes launched without energy shielding, opting instead for armor enhancements to save resources.
The operational challenges faced by the UNSC during confrontations with the Covenant limited their ability to research and implement shielding broadly. A user noted that โthe technology still required testing by the war's end,โ indicating that they prioritized immediate fleet readiness over comprehensive upgrades. The consequences of these decisions were stark; the aging UNSC fleet struggled against superior Covenant warships throughout the conflict.
