Space Force wants an EM&C integrator independent of its own developers. The Platform One Solutions Marketplace decides who can win it.

Who can respond to the Space Force EM&C system integrator notice, and by when

Space Systems Command wants a system integrator for its Enterprise Management & Control platform, independent of the contractors who write the platform’s code. If you run a cleared integration shop in the mid-market, this is new-business capture with a hard date on it. A five-page white paper by October 2, 2026 puts you in the down-select for a one-on-one at Space Industry Days on October 21 and 22. The award pathway runs through a Commercial Solutions Opening on the Platform One Solutions Marketplace. The notice asks for an awardable video there by the end of October so evaluators can assess it in time. The sources-sought notice went up September 18, 2026 under solicitation number EMC2026-001. No dollar value appears in it.

Separate three things before you spend a week on this:

• The independence rule is the competitive variable. As written it removes the firms with the deepest program knowledge from your competition.
• The two published dates run on different clocks. The later one governs whether your submission gets assessed in time.
• The term reaches five years only if every option is exercised. No value is stated anywhere.

Why the independence rule points away from EM&C’s own software developers

The notice splits the program into three contractor roles and keeps the integrator separate from the developers.

• Development Contractors write the core application code.
• System Engineering & Integration Contractors set the architectural roadmap and governance.
• The system integrator runs program increment planning, deployment automation, release orchestration and enterprise test and evaluation. It cannot write core code or set architecture.

The notice never defines “core software developers.” It does not say whether a development contractor could bid behind a mitigation plan or a firewalled affiliate. I take the clause to leave little room, because it reaches any core software developer and names no way around that. The standing federal conflict rule reaches a narrower group: a contractor providing systems engineering and technical direction. This bar is wider, which is why it reads as a competitive filter.

Which rules bind depends on the instrument. A commercial contract under the Commercial Solutions Opening falls under the standing federal conflict rules. An Other Transaction, cited in the notice as a governing authority, does not. There, independence binds only through the agreement’s own terms. A development contractor weighing a bid should put that to its own counsel first.

Accumulated EM&C knowledge now sits with firms whose position on this role is defensive. Integration and test experience is the currency here. EM&C familiarity does not substitute for it. Have you run enterprise system integration testing, regression testing and user acceptance testing on a classified program? Then you are in the set the notice is asking about. Write your white paper response to that.

The Platform One Solutions Marketplace gate that decides this first

The Platform One Solutions Marketplace is the access path here. Awardability on it is the binding constraint. Space Systems Command intends to solicit and negotiate under a Commercial Solutions Opening already live there. That is a competitive route for buying commercial solutions outside standard proposal mechanics. Getting listed as awardable means sending a five-minute pitch video through the marketplace portal for assessment. The notice asks responders whether they hold one now, and if not, what their timeline is.

That is a change of route. Prior EM&C phases were awarded as Other Transaction agreements through the Space Enterprise Consortium, which runs on membership. This one runs through a marketplace open to any firm with an assessed video.

Three dates, in the order they arrive:

1. Email a capabilities white paper to Dustin Lee and Kelly Greiner by 5:00 p.m. Pacific on October 2, 2026. Keep it to five pages, unclassified, in a single PDF.
2. Take a one-on-one session at Space Industry Days on October 21 or 22, 2026, if your white paper clears the down-select.
3. Get an awardable video onto the marketplace by the end of October 2026, so your submission can be assessed in time.

A firm can write a strong white paper, clear the down-select, sit through the industry day, and still have nothing an award can attach to. The white paper buys a conversation. Eligibility comes from the marketplace. If you lack that status, start the video this week. It is the access route for other Department of War buys too.

What EM&C is, before you write a capability claim about it

EM&C automates how satellite communications resources get allocated across the joint force. The platform adds real-time situational awareness. It ties enterprise data management together across the commands that consume it, from Combined Space Operations Command to the combatant commands. EM&C is not a satellite program. It is fielded software.

Those services group into four jobs:

• Registries of record: SATCOM terminal configurations and service provider profiles.
• Mission planning: separate wideband, narrowband and protected workup managers.
• Interference work: an event browser, spectral analysis tools and a global viewer.
• Command awareness: alerts consolidation, entity folders and capability status views.

The notice also names what the platform must reach, including two it identifies only by name, EMS Beskar and Blitzar.

A credible white paper names the DevSecOps toolchains you have run, the government software factories you have worked inside, and the classified environments you have tested in. The notice offers Kessel Run, Kobayashi Maru and Platform One as its own examples.

The firms with the deepest EM&C knowledge have the weakest claim to this role

Prior EM&C work traces to a Phase 2 engineering change award in December 2023. That went to a team led by RKF Engineering Solutions with Raytheon Intelligence & Space, Ascension Engineering Group and Kythera Space Solutions. An EM&C 2.0 award went to Knight Sky for the terminal registry. An MPRS component award went to NIC4, which Knight Sky later joined. The Air Force picked Hughes for an EM&C prototype in 2019. Auria bought RKF and Kythera in January 2026, putting two of those positions under one owner.

That chain rests on company award announcements. No government award record names those positions. The prior phases were awarded as Other Transaction agreements through a consortium, a non-FAR route with limited prime-level award visibility. Several positions are likely subcontracts under a consortium prime, which leave no prime-level record at all. The roster above is a working picture.

Five support contractors will help review submissions: The Aerospace Corporation, Emolbi LLC, Booz Allen Hamilton, Timonier Systems LLC and KBR Inc. The notice says nothing about whether those firms may compete. Mark your proprietary data carefully.

The award lands in the middle, with cleared integration firms that have software factory experience and no core-code position on EM&C. This notice carries no set-aside, so nothing in it restricts who may respond. A follow-on call under the marketplace opening could still be restricted.

• Check today whether your company holds awardable status on the Platform One Solutions Marketplace. If not, start the video.
• Pull your own past-performance record for integration testing, regression testing and user acceptance testing on classified programs.
• Confirm your facility and personnel clearance levels against a TS/SCI bar before you spend proposal hours.
• If you hold EM&C development or engineering scope, work out whether the independence rule reaches you, and what an outside integrator owning release and test removes.

The shaping window is open, and it closes October 2

This is a shaping window rather than a proposal window. The buyer, the program office, the contracting officer, the pathway and the dates are all identified. The requirement is still pre-solicitation. That is when a white paper and an industry-day conversation can move requirements before they harden. For a cleared mid-market systems integrator: respond, secure the one-on-one, and shape how integration scope and test duties get written.

Then segment by where you sit. A small firm under $10 million with facility clearance should compete on test and release-engineering depth, or take a subcontract position. No set-aside protects it here. A new entrant without a Department of War vehicle should pursue marketplace awardability either way. A current EM&C development or engineering contractor should be reading this defensively.

Watch for a Commercial Solutions Opening call against this requirement, or any disclosed value. Either turns this into an active pursuit. The notice auto-archives October 17, 2026, four days before the sessions it schedules. If that passes with no follow-on posting and no down-select, drop the priority back to monitoring.

FAQ

Can a company respond to the white paper without awardable status on the marketplace?

Yes. The notice asks responders who lack an awardable video for their plan and timeline to submit one. A response is welcome without it. The status matters at the other end, when an award has to issue through the marketplace opening.

What does awardable status on the Platform One Solutions Marketplace get a company?

It makes a company eligible to receive an award through the marketplace’s competitive procedures, once a five-minute pitch video is assessed. Awardable status confers no contract, authorization to operate, or security accreditation. Each buying customer still applies its own acquisition process.

Who owns the budget, and which contracting shop matters here?

The EM&C program office sits at SSC/TXM inside the Tactical SATCOM Division. Contracting runs through the Space Systems Command Directorate of Contracting at El Segundo, California. Operational demand comes from Combat Forces Command, US Space Command, Combined Space Operations Command, System Delta 88 Tactical SATCOM and the combatant commands.

Which companies hold the development and engineering roles today?

The notice names none. It refers to designated Development Contractors and System Engineering & Integration Contractors without identifying either. The working picture from company award announcements points to Auria, Knight Sky, Raytheon Intelligence & Space, Ascension Engineering Group and Hughes. Treat it as an inference.

What happens when the notice archives on October 17, before the industry-day sessions?

The posting disappears from public view four days before the October 21 and 22 sessions it schedules. The archive date is a posting default with no bearing on the schedule. Capture the contacts and dates now. If nothing replaces it and no down-select is announced, the signal weakens.
