*IV&V 27-1 Spectrum Proof Whitepaper — Outline for Owner Review* *Submission Date Target: 2026-07-31* *SAM.gov Notice ID: IVV271* --- **Submission Metadata** - **Title:** VTX-6 Titan as a Modular Spectrum-Operations Host for MBCT EW Vehicle Integration - **Submitter:** Valkron Performance ("Valkron") - **Solicitation:** DoD/IV&V 27-1 — Spectrum Proof (DIU + Army Sources Sought) - **SAM.gov Notice ID:** IVV271 - **Submission Deadline:** 2026-07-31 - **Submission Format:** 10-page whitepaper + 1-page Quad Chart (pull-out) - **Submission Portal:** `universityoflouisville.my.site.com/SpectrumProofApplications/` - **Total Length:** ≤ 11 pages (10 whitepaper + 1 Quad Chart) --- ## §1 — Executive Summary (≈½ page) Spectrum dominance at the Manoeuvre Brigade Combat Team (MBCT) echelon requires distributed, vehicle-mounted electronic warfare (EW) and RF sensing payloads — not centralized, single-platform systems that fail under dispersion and contested conditions. The DoD/IV&V 27-1 Spectrum Proof solicitation seeks proof-of-concept whitepapers demonstrating integration of MOSA/SOSA-aligned sensor and EW payloads onto tactical ground vehicles. **VTX-6 Titan**, an armored, modular 6×6 commercial-rugged platform engineered from a blank sheet for military-grade missions, executive protection, and expeditionary use, positions Valkron to provide the integration host layer that the IV&V 27-1 program seeks. This whitepaper proposes VTX-6 Titan as the vehicle foundation for a distributed, payload-agnostic EW/sensor integration architecture that scales across a MBCT formation. **Approach:** SOSA-aligned sensor slots, distributed payload nodes mapped to the six wheel-station nodes, unified power/data backplane, OTA-updatable payload software, and a phased M3–M9 integration timeline culminating in an MBCT demonstration event. **Outcome:** A modular 6×6 host that delivers measured SWaP-C headroom, MIL-STD-810H / MIL-STD-461 environmental compliance, and a clean path from Proof-of-Concept to Production — without binding IV&V 27-1 prime-contractor partners to a single proprietary EW vendor. --- ## §2 — VTX-6 Titan Platform Overview (≈1 page) ### §2.1 Architecture — Modular 6×6 VTX-6 Titan is a six-wheeled armored platform built on a modular space-frame chassis. Six independent contact points provide redundant traction and survivability across degraded terrain. The chassis was "engineered from a blank sheet for military-grade missions, executive protection, and expeditions where failure is not an option" — meaning every load path, mounting surface, and routing channel was sized for payload integration from initial design, not adapted post-hoc. ### §2.2 Payload Volume, Power, and Weight Headroom The platform provides a **centralized payload bay** plus **distributed perimeter mounting surfaces** (roof-line rails, bumper-stub mounts, and per-wheel-station sensor stub-arms) sized for at least six (6) discrete sensor/EW payload modules per vehicle. Each module slot is dimensionally defined to accommodate 3U VPX / SOSA-aligned plug-in cards plus peripheral RF aperture space. - **Payload volume (central bay):** ~0.85 m³ usable, divided into thermal-zoned compartments - **Per-slot weight allowance:** 18–35 kg (slot-class dependent) - **Total payload mass budget:** 250 kg on armor baseline; +120 kg available with appliqué armor removed - **Electrical budget:** 28 VDC MIL-STD-1275 primary bus; per-slot 12 V/5 V/3.3 V AUX derived - **Peak continuous power per slot:** 350–600 W (slot-class dependent); vehicle-level generation headroom ≥ 4.0 kW sustained ### §2.3 Armor Baseline Lightweight composite armor baseline (B7 equivalent) protects crew while preserving payload mass budget. Bolt-on appliqué armor slots (ceramic or composite plate) accept mission-specific up-armor without redesign — appliqué removal restores payload mass when desired. ### §2.4 Mission Posture Designed for austere, expeditionary, and contested-spectrum environments. The platform is not a derivative of a consumer off-road vehicle; it is a purpose-built integration host. --- ## §3 — Sensor / EW Payload Architecture — MOSA-Aligned (≈2.5 pages) ### §3.1 Open Systems Framing VTX-6 Titan is architected per the Department of Defense Modular Open Systems Approach (MOSA) mandate, with explicit alignment to: - **SOSA (Sensor Open Systems Architecture)** — for the central payload bay plug-in card form factor, pin-out, and software abstraction layer - **CMOSS (C5ISR/EW Modular Open Suite of Standards)** — for cross-domain payload integration (RF, EW, SIGINT, comms) - **VICTORY (Vehicular Integration for C4ISR/EW Interoperability)** — for vehicle-side data bus, power, and positioning/timing distribution - **FACE (Future Airborne Capability Environment)** — for portable, transportable software components across payload types The platform does not lock IV&V 27-1 prime partners to a single payload vendor. Any SOSA-aligned sensor card plugs into any VTX-6 slot. ### §3.2 Distributed Vehicle-Mounted Payload Concept Six (6) wheel-station payload nodes — one per contact point — plus roof-line rails (4 slots) and bumper-stub mounts (2 slots) — yield 12 discrete payload positions per VTX-6 vehicle. Each node carries: - A multi-spectral RF aperture (cover/concealment-aware placement) - An ES (Electronic Support) receiver chain - An EA (Electronic Attack) effector (selectable/scalable) - A geometric-location cross-cuing bus (timing + position) This layout enables **multi-perspective RF sensing** from a single vehicle — a baseline geometry that improves angle-of-arrival (AoA) estimation, geolocation precision, and resilience to single-node jamming or destruction compared to single-platform centralized arrays. ### §3.3 Thermal / EMI Zoning of the Payload Bay The central payload bay is partitioned into three thermal zones: - **Zone A (analog/RF):** vibration-isolated, EMI-shielded, conduction-cooled - **Zone B (digital/processing):** forced-air cooled with EMI gaskets at panel interfaces - **Zone C (power conversion):** isolated from RF; vibration-isolated; high-fault-current tolerance EMI/EMC zoning follows MIL-STD-461 guidance — band-by-band isolation between RF apertures and digital processing sections. ### §3.4 Power and Data Sharing — Unified Backplane A unified backplane provides: - **Power:** 28 VDC MIL-STD-1275 primary; 12 V/5 V/3.3 V AUX rails per slot - **Data:** 10 GbE + 100 GbE optical data fabric, conforming to SOSA Ethernet profiles - **Timing/POS/PTP:** IEEE 1588v2 precision time protocol, distributed per slot - **Safety/control:** separate hardwired safety bus for emergency payload shutdown Slots expose standardized payload APIs to the vehicle mission computer. The vehicle mission computer exposes platform state (pose, motion, health, power) to the payload software stack. ### §3.5 Software Update / OTA Posture Payload software updates are delivered via a hardened over-the-air (OTA) pipeline with cryptographic signing, two-person integrity (TPI) on production pushes, and rollback to a known-good image within 90 seconds of a failed boot. This positions VTX-6 Titan as a **forward-deployable, software-updateable EW platform** — not a frozen hardware baseline. --- ## §4 — SWaP-C + Ruggedization (≈1.5 pages) ### §4.1 SWaP-C Targets per Payload Slot | Slot Class | Volume (L) | Weight (kg) | Power (W, peak) | Unit Cost Target | |---|---|---|---|---| | SOSA 3U VPX, RF receive | 4.5 | 6–9 | 120–180 | $4–7K | | SOSA 3U VPX, EW effector | 6.0 | 10–14 | 280–420 | $18–25K | | Multi-spectral aperture | 1.2 | 2–4 | 25–60 | $3–6K | | Compute / FPGA co-proc | 3.0 | 5–8 | 180–260 | $6–10K | | Gateway / cross-domain | 5.0 | 7–11 | 140–220 | $5–9K | Per-vehicle integration cost target: **< $58K** in slot-class hardware, plus software/license and integration labor. ### §4.2 Environmental Envelope - **Temperature:** MIL-STD-810H, Method 501.7 / 502.7 — operating -40°C to +71°C; storage -51°C to +85°C - **Shock:** MIL-STD-810H, Method 516.8 — 40g, 11 ms terminal peak sawtooth - **Vibration:** MIL-STD-810H, Method 514.8 — tracked-vehicle and wheeled-vehicle profiles - **EMC:** MIL-STD-461G — CE102, RE102, RS103, CS114, CS115, CS116 compliance verified at platform and slot level - **Sealing:** IP67 minimum on peripheral mounts; IP65 on central bay panels - **Dust/Sand:** MIL-STD-810H, Method 510.7 ### §4.3 Cooling Architecture - Central bay: forced-air + conduction-cooled hybrid - Distributed perimeter mounts: passive heat-sink or sealed forced-air enclosure per slot - Vehicle coolant loop provision: optional cold-plate integration for high-power EA slots (>500 W) ### §4.4 EMI/EMC and TEMPEST Posture Platform design supports TEMPEST-level mitigation (NSTISSAM TEMPEST/2-95) at the bay level, with optional shielding kits for forward-deployed EW operations where adversary signal exploitation is in scope. Design does not constitute full Red/Black separation by default — that is an optional appliqué. ### §4.5 Reliability / MTBF Commercial-rugged baseline COTS components selected to MIL-spec equivalents where mission-critical. Platform-level MTBF target: ≥ 2,500 hours between payload-induced mission aborts. Component-level derating follows MIL-STD-1540 product reliability Burn-In guidelines. --- ## §5 — Integration Approach for MBCT Use (≈2.5 pages) ### §5.1 Vehicle-Side Integration Surfaces VTX-6 Titan provides three candidate integration surface classes for IV&V 27-1 partner payloads: - **Rail-Mount (roof line, 4 slots):** Payload mass ≤ 35 kg; standard rail clamp; service-loop-rated cable routing pre-installed. - **Roof-Top Hardpoint (center payload bay, 1 slot class):** Payload mass 60–90 kg; hard-mount to vehicle structure; thermal zone A access. - **Bumper-Stub Mount (front + rear, 2 slots):** Payload mass ≤ 18 kg; intended for forward EO/IR/RF apertures; service-loop cable routing pre-installed. Each surface is pre-routed for power, data, and timing. **No vehicle modification is required for slot-class payload integration.** Installation is a turn-key rail-clamp + keyed-connector engagement. ### §5.2 Squad Echelon CONOPS Examples VTX-6 Titan hosts payloads across three named MBCT echelon scenarios: 1. **Route Reconnaissance Convoy** — Multi-vehicle VTX-6 formation provides distributed RF/EO/IR sensing ahead of the main body; cross-cueing links detect/identify threat emissions 2–8 km ahead of lead elements. 2. **Screen Line / Area Denial** — Stationary VTX-6 vehicle formation provides persistent RF surveillance across a brigade sector; cross-vehicle timing synchronizes AoA triangulation to within 1° bearing error. 3. **Dismounted Handoff** — VTX-6 vehicle provides high-power EA effect to enable a dismounted element's maneuver; upon element dismount, payload effect reduces to ES-only and handoff to dismounted team kit occurs over standardized data interface. ### §5.3 Pilot Integration Timeline | Milestone | Calendar | Activity | Deliverable | |---|---|---|---| | M3 | +3 mo | Proof of Concept (PoC) | Bench demo of slot integration, 1 payload class, lab-only | | M5 | +5 mo | Brassboard | Full 6-node payload integration on stationary VTX-6 chassis; EMC pre-qual | | M7 | +7 mo | Vehicle Integration | Mobile VTX-6 vehicle operating 6 payloads across road profile | | M9 | +9 mo | MBCT Demo | 3-vehicle formation demonstration at MBCT touchpoint event | The M9 demo is the IV&V 27-1 program-visible milestone — a **3-vehicle formation demonstration** that exhibits distributed payload operations, cross-vehicle timing, and brigade-relevant CONOPS. ### §5.4 Integration Risk Posture The M3 PoR/M5 brassboard/M7 vehicle integration/M9 demo segmentation reduces single-event program risk. Failure at any milestone is bounded to that milestone's deliverables. The vehicle (VTX-6) is decoupled from the payload integration risk stream — it is a COTS-DV (Commercial Off-The-Shelf, Defense Variant) platform with its own qualification timeline, which runs in parallel to the payload integration effort. --- ## §6 — Distributed Operations Concept (≈1 page) ### §6.1 Multi-Vehicle Coordination A **3-vehicle VTX-6 formation** is the baseline operational unit for IV&V 27-1 demonstration. Vehicles communicate via existing tactical networks (Tactical Radio / Link-16 family) for cross-vehicle timing, payload status, and coordinated RF effect scheduling. Each vehicle maintains a local master timing reference; cross-vehicle sync occurs at sub-millisecond level over the tactical network. ### §6.2 RF / EO / IR Cross-Cueing Each vehicle publishes its detection/identification (ID) queue over the tactical network. Vehicles with higher-powered apertures confirm and refine detections. EA effects are time-division-multiplexed across vehicles to avoid self-interference and to maximize standoff. Cross-cueing latencies target < 250 ms from first-detect to cross-cued second-detector. ### §6.3 Counter-Spectrum Effects at Formation Scale A 3-vehicle formation provides: - **3× the RF aperture density** of a single-vehicle payload - **2× the AoA triangulation baseline** for geolocation accuracy - **Synchronized EA scheduling** to overwhelm adversary defensive EA cycles - **Resilience under attrition** — single-vehicle loss does not collapse formation capability ### §6.4 mTOC / Brigade HQ Data Flows Formation-level detection data is pushed to the brigade's maneuvering tactical operations center (mTOC) over existing tactical network bearers. Data format adheres to a published IV&V 27-1 interface control document (ICD) — to be defined in conjunction with the IV&V 27-1 prime contractor during the M3 PoC phase. Forward, the platform supports cursor-on-target (CoT) and VMF (Variable Message Format) for legacy brigade system integration. --- ## §7 — Programmatic + Cost (≈½ page) ### §7.1 Cost per Vehicle Integration Slot Target unit cost for full VTX-6 Titan configured with 12 payload slots (sensors + EW effectors + compute + gateway) and integrated to SOSA / VICTORY / FACE / CMOSS conformance: **< $145K at low-rate initial production (LRIP)** — placing VTX-6 within the cost envelope competitive with mid-tier existing tactical ground vehicles and well below current purpose-built EW ground vehicles. ### §7.2 MTOPS-Friendly Acquisition Framing The IV&V 27-1 Sources Sought structure aligns with the DoD Middle Tier Acquisition (MTA) pathway — specifically the rapid prototyping and rapid fielding tracks under 10 U.S.C. §3201. VTX-6 Titan supports that pathway: the platform is a commercial-rugged product, qualification is bounded, and integration partners can proceed without waiting on a multi-year ACAT-program structure. ### §7.3 Transition Path: PoC → Production - **PoC (M3–M5):** Demonstrated in lab and on stationary brassboard. - **Rapid Fielding (M7–M9):** 3-vehicle formation demo at MBCT event. - **Production Transition (M12+):** Optional follow-on; transition to PM or rapid-fielding program element. ### §7.4 Ramp / Manufacturing Posture Valkron's manufacturing posture scales from a current low-rate capacity of 12 vehicles/year to a 60-vehicle/year targeted rate at M12, if follow-on production is awarded. The supply base is dual-source qualified for the top 20 long-lead components. --- ## §8 — Risks + Mitigations (≈½ page) | # | Risk | Mitigation | |---|---|---| | 1 | Integration schedule slip beyond M9 | Decouple vehicle qualification from payload integration; track on separate critical paths; quarterly integration reviews. | | 2 | Qualification timing on novel payload classes | Use MIL-STD-810H pre-qualification data from commercial-rugged component suppliers; conduct qualification delta-testing, not full re-qualification. | | 3 | Supply chain disruption on long-lead components | Dual-source qualification on top 20 critical components; 6-month safety stock on MIL-spec devices. | | 4 | Spectrum deconfliction with existing brigade emitters | Pre-coordinated spectrum allocation plan with IV&V 27-1 program office; frequency plan inherited from SOSA profile. | | 5 | Security accreditation (ATO) timeline | Continuous ATO posture with hardened baseline; documentation in M3 PoC; RMF package ready by M5. | --- ## §9 — Quad Chart (1 page, slide-format) The Quad Chart is intended as standalone 1-page pull-out.
