By the Defence Act of 2000, the government considered that only four air defense battalions were needed in the future organization.

This was because the operations of Gotland Anti-Aircraft Corps were considered too limited to be able to be developed into a single unit for the country's air defense.

For Norrland Anti-Aircraft Corps, the government considered that it would result in serious loss of skills in the short perspective of locating the entire air defense function to Boden.

The advantage of maintaining Roslagen Anti-Aircraft Corps was, among other things, good training areas and that the Air Defence Combat School (Luftvärnets stridsskola, LvSS) was located in Norrtälje, which also had an experimental site on Väddö training area.

This was something that was considered to be an advantage for Göta Anti-Aircraft Corps, as it was already part of a garrison that housed both a military college and the Swedish Armed Forces' Halmstad Schools (Försvarsmaktens Halmstadsskolor, FMHS).

The government came, in its bill regarding the Defence Act of 2000, therefore, to disband Roslagen Anti-Aircraft Corps and maintain the Göta Anti-Aircraft Corps as it had greater and better opportunity for garrison coordination with an expanded infrastructure to cope with increased mechanization of the air defense.

From 1 July 2000, the operations went over to a decommissioning organization, called the Avvecklingsorganisation Norrtälje, until the disbandment was completed by 31 December 2001.

South of Norrtälje, between County Road 276 towards Åkersberga and Lake Limmaren, Roslagen Anti-Aircraft Corps had an area called Mellingeholm.
