B-2 Spirit / Advanced Technology Bomber: Senior Ice vs Senior Peg
Official line: Northrop’s flying-wing B-2 won a classified Advanced Technology Bomber contest and delivered stealth penetration. The declassified museum, OSI, and GAO trail is sharper. Senior Ice (Northrop/Boeing) beat Senior Peg (Lockheed/Rockwell) on 20 October 1981 inside a black program that later grew to tens of thousands of cleared people—while cost, concurrency, and redesign politics stayed in oversight paper long after the shape became public. The rabbit hole is not a continuing invisible bomber cabal. It is how a SAP shootout became an industrial secret, then a GAO spreadsheet.
The Contest
The Advanced Technology Bomber effort took shape around 1979. Two teams carried the designs that matter for this page. Northrop with Boeing offered Senior Ice: a curved flying wing that became the B-2 Spirit. Lockheed with Rockwell offered Senior Peg: a faceted concept carrying Have Blue / F-117 family DNA. Caption-ready clock: Ice wins on 20 October 1981. That date is the competition outcome the museum and OSI language still treat as the clean selection hinge—not a rumor that Peg somehow flew in secret afterward. Peg’s losing design details remain thinner in official public packets than Ice/B-2; absence of a Peg exhibit is not proof of a Peg fleet.

Official Posture: Black Funding, Later Reveal
ATB lived under black-program funding and special-access security. The public “stealth bomber” reveal came years later. Museum and OSI language remains the cleanest official naming of Senior Ice, Senior Peg, and the later Senior Cejay (Senior C.J.) lineage that OSI ties to the B-2 security culture and to Tacit Blue adjacency. Prefer those packets over War Zone art galleries that reconstruct Peg as if the losing design were as well documented as the winner. Special-access rules scaled with the subcontract web: LO coatings, avionics, and structural work spread across cleared industry long before the flying wing had a public name.

Tacit Blue is sibling LO culture—classified demonstrator feeding security habits and shaping habits—not a clone of the ATB competition evidence list. Cross-link. Do not merge.
What the Paperwork Shows
Selection of the Northrop design as B-2 Spirit is settled. Mid-1980s mission shift forced high-altitude assumptions toward low-altitude terrain-following redesign. Planned force structure collapsed from on the order of 165 aircraft toward roughly 21 operational airframes in GAO-era accounting. Those numbers belong attached to named GAO reports, not to viral “trillion-dollar plane” slogans. Concurrency—building while redesigning—shows up as oversight language once Congress could score the program after it left deep black. Early public-era GAO status products and later cost/operational issue reports are the FOIA-adjacent spine: what oversight could say once the bomber was no longer deep black.

Why the Story Stayed Managed
Low-observable signatures, the subcontract web, and the penetration mission justified SAP compartmentation. OSI’s narrative of tens of thousands of program personnel and hundreds of cleared subcontractors shows how “black” scaled into industrial secrecy—not a two-person garage myth. Jack Northrop’s late briefing into the program under oath, where primary text names it, is color on the flying-wing lineage, not proof of a parallel Peg fleet. Contested overclaims to refuse: Senior Peg secretly built and flown; Aurora-as-ATB conflation; unsourced RCS numbers pasted onto either design. Ice versus Peg is a documented competition outcome. Peg’s thinner public paper trail is a documentation fact, not an invitation to invent flights.
Oversight After the Unveil
Once the bomber left deep black, GAO cost and concurrency reports became the readable public spine. Dollar figures stay tied to those PDFs. The tension readers feel is real: a competition decided in 1981, a shape the public only later learned to call B-2, and years of acquisition politics that oversight paper captured better than press kits. Have Blue / F-117 and Bird of Prey sit on the LO family graph as precursors and later demonstrators. This page owns the ATB shootout and the GAO afterlife—not every black-triangle rumor that borrowed the Spirit’s silhouette.
Date discipline prefers museum and GAO chronology for first flight and unveil over magazine roundups. The flying wing the public learned to recognize was the end of a classified contest, not the beginning of an Aurora sequel. Readers chasing a secret Peg squadron will find thinner official paper than Ice’s trail—and that thinness is itself evidence about what the government chose to declassify, not a blank check for folklore. Keep dollar claims glued to NSIAD report numbers. Keep RCS claims out unless a named primary packet states them. The Archive’s job here is Ice versus Peg as competition history with an oversight afterlife, not a stealth-mythology clearinghouse.
What the Paper Trail Settles
Settled on the documents: ATB competition ending with Senior Ice selection on 20 October 1981; B-2 as the public aircraft that followed; Tacit Blue adjacency in official security culture; GAO accounting for cost, concurrency, and force-structure collapse after unveil; OSI language naming Ice / Peg / Cejay. Overclaim to refuse: Peg as a secretly flown twin, Aurora conflation, and RCS folklore without packet citation.
The tension that remains is the one the packets leave open. Officials eventually displayed a flying wing. For years the contest, the redesign, and the industrial clearance footprint stayed managed. Senior Ice versus Senior Peg is that managed contest—read beside Tacit Blue and the GAO files, not beside Aurora lore.
