Impacts to breach.
27 design-basis vehicles plus custom, every one swept against the same line and ranked by fastest breach. EV super-trucks lead the light-vehicle threats.
PNH Security Engineering · Hostile Vehicle Mitigation
Model the repeated attack. Quantify the delay it buys.
A rating stops one impact. A raid brings thirty. VECTOR-D turns a rated line into a time budget: how many deliberate impacts the line takes from short standoff, and how much time that buys against your declared response. VECTOR answers how fast is it going when it arrives; VECTOR-D answers how many times, and how long.
Screening estimate
Breach between impact 26 and 31, 2.4 to 2.9 minutes. That exceeds the documented abandonment window of about 2 minutes but not a typical response benchmark, so the line buys deterrence and verification time, not a full response.

- Screening companion to NPSA VADS
- LPS 1175 vocabulary
- ISO and ASTM anchors
Not a VADS rating. NPSA is the sole VADS authority. LPS 1175 is used as vocabulary only; it tests manual tool attacks, not vehicles.
199 rating anchors across 5 standards (ASTM F2656, ASTM F3016, ISO 22343-1; IWA 14-1 and PAS 68 as legacy) · vehicle library per VVA-M-01 Rev 1.1. Three calibration tiers: Tier 1, illustrative defaults for screening; Tier 2, finite-element calibration per product family; Tier 3, anchored to repeated-impact test history.
What VECTOR-D does
Time to breach and verdict.
Bands against your declared response benchmark and the documented abandonment window. The conservative bound governs.
Transparent on every page.
Assumptions, gaps and sensitivity: printed, not hidden.
What VECTOR-D computes
01
Per-impact energy
A traction-limited standing start over the standoff the attacker can actually use, on the best surface they can reach. Both models run on every result — the closed form and the VVA-M-01 forward pass with the vehicle's full parameters — and each is reported as a cross-check on the other. Reverse strikes carry the stiffer rear structure.
02
Damage accumulation
Damage accumulates against the capacity anchor — the certificate's tested class energy, discounted by the failure mode — under a three-phase efficiency curve. Two curves are always run, so the answer is a band from the conservative bound to the best estimate. Single-point values are never quoted.
03
Delay verdict
The attack cycle turns impacts into minutes, keyed to the conservative bound against the response time you declare and the ~2-minute documented abandonment window. Delivered as a documented report with the full input register, assumptions and limitations — or as an engineer-reviewed and signed issue.
