Summa Deep Space Incident

From Halopedia, the Halo wiki

The Summa Deep Space Incident,[1][2][3] sometimes referred to as the Summa Space Incident,[4] was an event that was classified to the highest levels.[1] The incident sparked research into extra-vehicular activity technology, which would go on to create the technology used in the OF92 Booster Frame.[5] and the Booster Frame itself was also developed in tandem with this research.[3]

Feedback and data from the incident itself helped the rapid development and improvement of EVA-class Mjolnir.[2][1][4]


The name could be a reference to the Battle of Summa, one of the major battles of the Winter War in 1939-1940.
