The defense primes closed September 15 2026 at LMT 533.46, RTX 195.50 and NOC 531.25, against 524.46, 197.55 and 515.57 on September 9 - LMT up 1.7% and NOC up 3.0% while RTX slipped 1.0%. After two consecutive escalation windows in which all three fell, this is the first in which the group rose through an escalation, with the Houthi front and the Iraqi-launched pipeline strike widening the war's geography.
