VANGUARD DYNAMICS // SUBSURFACE FACILITY NODE ALPHA SUBLEVEL 3: QUALITY ASSURANCE & FLIGHT TELEMETRY LOG DOCUMENT REF: LOG-MKP12-TA01-FLT01 CLASSIFICATION: EYES-ONLY // ENGINEERING CORPS PROJECT: MKP-12 Hyperion Platform ARTICLE: VG-MPK-12-01 (Test Batch 01 / Unit 01) CONFIG: Ballistic Test Vehicle (BTV) / 1T Telemetry Payload TEST SITE: Silo Complex Alpha-04 (Northern Ocean Launch Corridor) [PRE-LAUNCH SEQUENCE] T-00:15:00 - Sublevel 10 Geothermal Grid reroutes power auxiliary loops to Silo 04 pneumatic lock gates. Pressure equilibrium confirmed. T-00:05:00 - Avionics self-test complete. Primary guidance bus synchronized with Node Alpha surface array. T-00:01:00 - Silo vent scrubbers activated. Silo hatch locks retracted. Ambient chamber temperature: -14°C. T-00:00:10 - Ignition sequence initiated. Auto-sequence handed over to flight logic. T-00:00:00 - Primary pyrotechnic igniter sequence command issued. [FLIGHT EVENTS & TELEMETRY SUMMARY] T+00:00:01.2 - Primary solid propellant grain ignition achieved. Mass flux build-up nominal. Vehicle clears Silo 04 lip. T+00:00:08.5 - Vehicle enters primary ascent corridor over the northern strait. Vector deviation within <0.2° tolerance. T+00:00:24.0 - Velocity: Mach 1.8. Transonic shockwave passes clean across composite airframe. Internal vibration sensors read nominal. T+00:00:41.1 - Vehicle approaches Maximum Dynamic Pressure (Max-Q). Altitude: 11,400m. T+00:00:41.8 - ANOMALY DETECTED: Rapid pressure spike logged in SRB combustion chamber (Chamber Pressure >145% nominal rating). T+00:00:42.1 - Casing thermal-structural failure. Microscopic stress fracture or propellant grain void suspected near mid-body weld ring. T+00:00:42.3 - Casing integrity compromised. Dynamic over-pressurization leads to catastrophic mid-air disintegration. High-velocity fragment cloud dispersion logged over open ocean. T+00:00:42.5 - Telemetry link lost. Flight Termination System (FTS) auto-triggered on residual payload debris. [POST-FLIGHT ENGINEERING DIAGNOSTIC] STATUS: CRITICAL FAILURE / TEST ARTICLE DESTROYED PRIMARY CAUSE: Extreme-density solid motor casing structural breach during Max-Q stress peak. Internal pressure exceeded carbon-composite structural tolerances, leading to explosive chamber rupture. ACTION ITEMS FOR ARTICLE VG-MPK-12-02: 1. Dispatch Sublevel 5 recovery team via Node Alpha maritime sea-drone to retrieve telemetry core remnants from the strait. 2. Re-evaluate binder chemistry and thermal expansion tolerances on high-density grain matrix to eliminate internal propellant voids. 3. Sublevel 2 manufacturing line instructed to halt assembly on Article 02 pending structural casing reinforcement reviews. 4. Issue internal flight incident report to R&D division.
