Stealth Armor Systems is seeking industry feedback on NIJ Armor Standard 0101.07 (2023)

Stealth Armor Systems is seeking industry feedback on NIJ Armor Standard 0101.07 (1)John Sun Data:

we sat down
While you have some great ideas here, I think you have some unrealistic expectations from the NIJ when it comes to ballistic threat testing. While I would like to see more comprehensive and rigorous ratings, keep in mind that the NIJ is a civil/domestic LE rating system. It is intended for civilians and law enforcement to protect themselves from everyday domestic threats. Your qualifications proposed here seem really designed for the military to counter peer-to-peer threats, which I feel is unnecessary for Conus. It's also important to remember that the more subjects you want, the higher the costs, which in turn are passed on to the end user/consumer. Each test lap is loaded individually to ensure sufficient speeds. Current NIJ speeds are already generally a realistic worst-case scenario. I think the only thing that might be missing here is the size of the cost factor for retail and LE customers.

In my opinion it would be better to have more skill levels with less types of trial rounds. For example, test for 7.62×39 API and M855A1 instead of M855, 7.62×39 MSC, M855A1 and 7.62×39 API. M855A1 and API 7.62×39 are bigger threats than MSC and M855, so there shouldn't be a need to test those rounds either. There must be enough overlap.

Also, I think having ratings for M2AP or foreign hardened steel core threats at >3000 FPS is unnecessary. The current NIJ .06 Tier 4 rating already represents the M2 AP Hardened Steel Core at 2880 +/- 50 FPS. In fact, this speed is already faster than you would normally see with excess M2 AP. The NIJ hand loads these rounds and fires them from a 22" barrel to achieve their velocities. Also, for foreign threats I will only use 7.62x54R 7N13 as part of the Russian BR5 classification as my example which is a core projectile of 148 gram hardened steel which they test at 2723 +/- 49 FPS This will be a similar threat to the M2 AP and I think there is no need to test it against other foreign AP threats which function similarly and are incredibly rare of find in the USA.

With that said, I would personally suggest this. This represents common CONUS threats. (This is just a rough idea.)

RF1: Bola M80 (6x 2780 FPS), M193 (6x 3250 FPS), M855 (6x 3150 FPS)
RF2: Bola M80 (6x 2780 FPS), M855A1 (6x 3150 FPS)
RF3: 7,62x54R FMJ (3x 2760 FPS), 0,30-06 FMJ (3x 3000 FPS), M855A1 (6x 3150 FPS)
RF4: 0,30-06 M2AP (3x 2880 FPS)

I assume RF1 would cover mild steel core and FMJ threats. I agree with you, the proliferation of PE boards that fail to stop the M855 is worrying. The use cases are incredibly specific, and most people buy these boards without realizing they're not impeding the steel core.
Also, I think RF2 would be a "Light AP" rated board (I know A1 is not AP), I think RF3 would be a "Light AP" plus FMJ Hunting Rifle / Large Caliber Rifle Protection, and then RF4 would be a more complete protection AP.
I'm not sure if RF3 is needed or not and if it should be included in RF4.

Their numbered rounds of 7.62×39 MSC and M855 would be covered by RF1 and later. Its M855A1 numbered round would be covered by RF2 and higher. Its numbered 6.8mm NGSW (FMJ) cartridge would be covered by RF3 and higher. So 7.62x54R MSC, M80A1 and M2 AP would be covered by RF4.

In my opinion, your RF4 and RF5 threat profiles are unnecessary for CONUS. The shorter barreled M995 and M993 (16") can already be stopped quite often with domestic Tier 4 disks. If we talk about speeds of 3200-3400 FPS, this would not stop, but I think it would probably be unnecessary. The current ESAPI Rev J is rated for 3 shots of the M995 at 3350 FPS however only the XSAPI is rated for the M993 at 3200 FPS (I think the LTC 28595 is too but not sure).

RF5 would be an incredibly specific use. 50 BMG boards actually exist in the United States, they were originally made by Ceradyne for helicopter pilots and static defense. These were rated for 50 BMG FMJ. Well, the Russian GOST BR6 classification covers 12.7 x 108 mm API, but again, this is a military classification system and I don't think it's strictly necessary to use CONUS.

The threat ratings you describe would be great if we merged our military and civilian armor rating system, but I don't think that's entirely feasible or a wise choice as both will face very different threats.
He mentioned that our industry is currently stagnant, the civilian industry, but mainly because of the cost. The really innovative shielding systems are incredibly expensive (you can bet companies like Ceradyne or LTC are innovative). Only a limited amount is possible with inexpensive materials such as alumina ceramics, fiberglass, aramid and less expensive PE. As I mentioned earlier, cost is a major barrier for the civil defense industry, most civilians and law enforcement cannot afford the armor that the military pays for. So the cheap materials we have to work with are limited.
If Honeywell and DSM suddenly cut their PE prices, or Cerco, Bitossi and Coorstek suddenly cut their boron carbide and silicon carbide prices, I'm sure we would see a lot more innovation in the construction industry. However, due to costs and the resulting low demand, it is currently not worth squeezing the juice. Furthermore, there are so many ways to make a ballistic plate these days that the next leap in innovation must come from materials. We have been using (mostly) the same materials since the 1970's and 1980's, it's clear that the individual components have improved as we now have Dyneema HB212 or SB117 and better ceramic manufacturing processes and ceramic reinforcement techniques. But none of that would bring a big jump in performance.
I've read a bit about potential new materials like boron suboxide, aluminum dodecabiride, and AlMgB14. I'm not a materials scientist so I just read it for fun, but it seems the general consensus at the moment is that these materials show promise but are too expensive and difficult to synthesize to be commercially viable at this time. (There's a little post on the Diamond Age blog about this.)

Now for the points I completely agree with you on (because there are a few).

1. I completely agree with the "multi-hit" protection. NIJ .07 changed the requirements for the M80 ball to 3 shots and set the round count for the M855, 7.62×39 MSC and M193 to 3 shots each and then increased the number of test fields required. I think they should have stuck with 6 shots each.
You can now certify up to 3 M2 AP shots with the RF3 NIJ 0.07 (draft), but honestly I think 2 should be the minimum. This mainly serves to prevent ceramic tiles from being constructed erroneously without a suitable adhesive bond between the ceramic and the support (eg AR500...).
2. I completely agree with the reduction of the minimum lateral distance throw. Now I can understand your reasoning behind this first. The edges of a ceramic plate have reduced performance, especially with round APs like the M2 AP. This is mainly due to the fracture conoid (Hertzian crack) not having enough space to develop properly, reducing the amount of ceramic material with which the indenter core interacts. Too bad it was misused. I think it should be shortened to 1 inch and there should be a requirement for full edge-to-edge ceramic coverage.
3. Quality Control and LIABILITY.
This is something I've been screaming about for over a year now (and people seem to ignore me). BRAND CHANGING OF CHINESE LICENSES SHOULD BE ILLEGAL. REPEATED NIJ AUDIT ERRORS (CUSTOMIZATION ERRORS) AND RECALLS MUST HAVE ACTUAL CONSEQUENCES. It's absolutely amazing how some companies (I won't name names) seem to legitimately not be interested in their end users.
There is currently some level of NIJ testing and follow-up inspections (FIT) responsibility for certified boards, but I don't think this happens often enough (only once every 2 years for ISO certified companies) and there are no real consequences for NIJ audit error chains and recalls. Many people don't even know that the NIJ recommendation list exists, I'm sure some people would be incredibly surprised to see how often some brands fail the FITS.

If you've been at this this long, thanks for listening to my babbling. In general, I think I agree with most of your points. I just disagree with your suggested test rounds, I think they would be better suited to a military ranking system.
