Defence Readiness & Sub-Tier Bottleneck Workbench.
Select your operational role or run a 2-minute bottleneck diagnostic to see why conventional NAICS directories, ERP spend cubes, and generic AI break at Tier-2 and Tier-3—and open the exact 15Rock Review teardowns built for your decision.

Modeled forward naval readiness bridge (+C$35M/yr ISS efficiency)
Across multi-decade naval shipbuilding and In-Service Support (ISS) programs, 62% of spares-related vessel downtime traces back to 18 long-lead sub-tier valves, shaft seals, chillers, and switchgear—while Tier-2 fabricators bill blanket 28% alloy scrap rates.
ERP spend cubes stop at Tier-1 invoicing and cannot see whether three competing Tier-1 integrators rely on the same single-furnace Tier-3 forging house. Without bottom-up CAD nesting and CNC spindle-hour physics, buyers cannot challenge a 32% sole-source price hike.
- 01Physics Should-Cost Bridge: Deconstruct top 50–250 BOM SKUs into finished CAD part weight vs. gross alloy billet, true 14.2% nesting scrap, and deterministic 5-axis spindle hours.
- 02Civil Nuclear Cross-Walk: Query 15Rock's industrial graph for 14 domestic ASME Section III / CSA N285 nuclear and severe-service energy shops to qualify alternate sources.
- 03Rotable NSN Scrub: Reconcile duplicate NATO Stock Numbers across coastal depots and link safety stock to sub-tier lead-time variance.
Anonymized Benchmark from Delivered Work
Following DND's observed fleet serviceability recovery from 45.73% (FY23–24) to 59.6% (FY24–25), modeled a +15.4-point forward availability bridge toward the 75.0% target via 14 domestic nuclear/energy alternate shops (protecting C$104M–C$260M in cumulative 35-year lifecycle fee-at-risk on a C$5.2B ISS program), plus a 535 bps (US$143.6M / C$194M direct COGS; C$329M combined with C$135M SG&A) margin bridge across a US$2.68B structural platform.
- Isolate the exact 18 sub-tier mechanical/electrical assemblies driving 62% of spares-related platform downtime.
- Require suppliers to unbundle raw mill alloy index pass-throughs from conversion spindle hours.
- Cap NADCAP NDT, heat-treatment, and hydro-testing charges as fixed lot fees rather than percentage adders.
- Cross-qualify 14 domestic civil nuclear (ASME Section III / CSA N285) fabricators against foreign single-source naval valves and heat exchangers.
Breaking the Shipyard & Sustainment Bottleneck: Physics Should-Cost Teardowns and Sub-Tier Readiness Across Naval Programs
Observed 45.7% → 59.6% DND baseline, modeled +15.4-pt bridge to 75% via 14 alternate shops, and 535 bps (US$143.6M / C$194M) COGS teardown.
The NAICS Blind Spot: Why Sovereign Defence Supply Chains Break at Tier-2 and Tier-3
88.4% (517 of 585) of compiled defence-capable sub-tier plants are registered under non-defence commercial NAICS codes.
