Gelb was complete, and the OKL prepared for Case Red. The Luftflotten were reorganised; Sperrle retained II. and V. "Fliegerkorps" along with I. "Flakkorps". The flak corps was reorganised into two brigades, with four regiments each with the firepower of 72 batteries. Sperrle was required to strike far deeper into France, and was given the majority of "Zerstörer" (destroyer aircraft) equipped with Messerschmitt Bf 110—half of them given to Greim and Loerzer. Sperrle could muster 1,000 aircraft. On 5 June, Sperrle's order of battle lists Richthofen's VIII corps and Massow's Jafü 3. Opposing them was 2,086 aircraft of the "Armée de l'Air", but production of aircraft was not matched by component manufacture, and only 29 percent were operational.
