McCurdy's Armor®
Level 1 Armor
Configuration


PS-EV-001


1.0 Purpose:

The purpose of this document is to define the performance, areal density, and general features of DDM's McCurdy's Armor® - armor configuration Level 1.

2.0 McCurdy's Armor®:

McCurdy's Armor® (Portable Armor Wall System) is a rapidly deployable armor system comprised of frames and panels that can be configured in various walls and enclosures to provide various levels of ballistic and blast protection depending on mission requirements.

3.0 Ballistic Performance at Level 1:

DDM has defined Level 1 by a single layer 1/4" armor alloy steel at approximately 10.2 pounds per square foot.

The steel armor materials are purchased to a ballistic specification of:

  • NIJ Level 0108.01, Level III, which corresponds to 5 shots with the 7.62 x 51 mm M80 Ball, full metal jacket (FMJ), 150 grain bullet, lead core at 2750 +/- 50 feet per second (fps), which is muzzle velocity.

This specified steel has also demonstrated protection against the following threats.

Threat Description Results1
7.62 x 54R LPS Ball, FMJ, 150 grain bullet, mild steel pin core, sniper round, Dragonov rifle. Muzzle velocity is 2780 fps. V50 > 2850 fps at 0 deg
7.62 x 39mm M1943 PS Ball, FMJ, 122 grain bullet, mild steel pin core, AK-47. Muzzle velocity is 2380 fps. obliquity
5.56 x 45mm, M855, FMJ, 62 grain bullet, hardened steel core with lead pusher, AR 15 (M 16). Muzzle velocity is 3050 fps. V50 > 3050 fps at 0 degree obliquity
0.50 Caliber FSP (MIL-DTL-46593B), 207 grain, chisel nosed cylinder, 30 Rockwell Hardness C Scale at 0 degrees obliquity. V50 ~ 2000 fps in panel


Note 1: V50 defined in MIL-STD-662 for example.

Armor wall panels are held in place on the McCurdy's Armor® frame by twisting a lock handle on the outside of the armor which engages an internal locking bar. This locking bar mechanism has been tested:

  • Welded lock handles have stopped the M80 ball at 2713 fps and the LPS ball at 2854 fps.
  • Against the 7.62 x 51 M80 ball, an improved mechanically assembled lock handle demonstrated a V50 > 3250 fps for a direct hit.

Armor wall panels are equipped with 2 lift handles welded into place. These lift handles have been tested at the weakest area just outside the welded joint on the steel:

  • Against the 7.62 x 51 M80 ball they demonstrated a V50 = 2639 fps for a direct hit.
  • DDM is working to improve this performance and recently tested a prototype handle attachment achieving a V50 = 2743 fps.

Armor wall panels have been tested at welded hooks and along the bent lip within a system configuration:

  • Against the 7.62 x 51 M80 ball they demonstrated a V50 ranging from 2608 to 2786 fps.

2.0 McCurdy's Armor®:

McCurdy's Armor® (Portable Armor Wall System) is a rapidly deployable armor system comprised of frames and panels that can be configured in various walls and enclosures to provide various levels of ballistic and blast protection depending on mission requirements.

3.0 Ballistic Performance at Level 2:

DDM has defined Level 2 by two layers 1/4" armor alloy steel separated by the width of the McCurdy's Armor® frame.

The steel armor materials are purchased to a ballistic specification of:

  • NIJ Level 0108.01, Level III, which corresponds to 5 shots with the 7.62 x 51 mm M80 Ball, full metal jacket (FMJ), 150 grain bullet, lead core at 2750 +/- 50 feet per second (fps), which is muzzle velocity.

This specified steel as a single sheet has also demonstrated protection described in the McCurdy's Armor® Level 1 document. In the Level 2 configuration the steel armor has been tested against various threats as listed below.

Threat Description Results1
.30-06 AP-M2, 166 grain hard steel core. Muzzle velocity is 2760 fps V50 > 2900 fps at zero degrees obliquity
.50 Caliber AP-M2, 708 grain hard steel core. Muzzle velocity is 2845 fps. At 200 meter range velocity is 2555 fps from the 36" barrel. V50 ~ 2550 fps at 30 degrees obliquity

Note 1: V50 defined in MIL-STD-662 for example.

Armor wall panels are held in place on the McCurdy's Armor® frame by twisting a lock handle on the outside of the armor which engages an internal locking bar. This locking bar mechanism has been tested:

  • Against the 0.30 Cal AP-M2 for direct impact on the locking handles there were no penetrations of six shots from 2953 – 3648 fps.
  • Against the 0.30 Cal AP-M2 for direct impact over the welded portions of the hooks the V50 was over 600 fps above muzzle.
  • Against the 0.30 Cal AP-M2 for direct impact over the bent lips in the system, the V50 wasover 600 fps above muzzle.
4.0 Blast Performance at Level 2:

McCurdy's Armor® systems in wall and corner configurations with Level 2 armor, steel front and back, with stanchions and with or without ground stakes have been tested against 32.8 lbs of TNT. At 15 foot range for a corner configuration and 20 feet for wall configurations, McCurdy's Armor® structure withstood the forces from the blast remaining erect and with all back side armor panels intact.

In tests against an IED with 32.8 pounds of explosive wrapped in 3/8" mild steel cubes for fragmentation, level 2 armor positioned on the top third of a corner set-up withstood the forces from this threat at 9.98 feet (3 meter) range.

McCurdy's Armor:
Thailand Military Test Summary


FRM-501


1. Summary:

Recently, a live fire test was conducted by the Thailand military in January 2012 in order to evaluate McCurdy's Armor. The Improvise Explosive Device (IED) used in testing was built by the customer to simulate threats that are currently being used against them in theater, with a standoff that they deemed to be realistic. The test configuration of McCurdy's Armor is shown in Figure 1. This live fire test was conducted for the expressed purpose of demonstrating McCurdy's Armor to the Thailand military. The data collected was purely empirical and documented through visual checks and pictures.

2. Blast and Fragmentation Evaluation

2.1. McCurdy's Armor Setup

McCurdy's Armor was configured to facilitate testing of two different protection levels. The two protection levels tested were McCurdy's protection levels: MP and XP Plus. MP protection is defined as two single McCurdy's Armor panels separated by the width of the standard aluminum frames for the system. XP Plus protection is defined as two single McCurdy's Armor panels separated by the width of the standard aluminum frame with sand sealing the area between the panels.

This configuration (McCurdy's Armor – U Kit) consists of a three sided structure with each side having two McCurdy's Armor panels wide and three Armor panels high. The forward facing side was divided into left and right configurations with the XP Plus configuration being the lower left two armor panels when facing the threat and the MP protection level being the right two lower armor panels. The third row up was assembled using double armor gun ports which included a transparent armor hinged window. The angled corners of the kit consisted of McCurdy's Armor double armor panels on the top row and single armor panels on the lower two rows. The roof assembly was not included in the live fire test.

2.2. Blast and Fragmentation Setup

2.2.1 Threat Location

The live fire setup consisted of McCurdy's Armor U kit with an IED placed at a distance of 3 meters (9.8 feet) in front of McCurdy's Armor as shown in Figure 1.

2.2.1 IED Description

The IED used in testing was assembled by the customer using 1 lb. of C4, 15 lb. of TNT, and 10 lb. of mason nails packed in a propane tank (See Figure 2, below).

3. Live Fire Results

McCurdy’s Armor system was extremely successful in defeating this IED threat.  Frame assemblies assisted in mitigating the blast force and still had enough structural capability to hold the armor protection in place (see Figure 3, below).

Based on the results of this live fire test, it was found that McCurdy’s Armor in both the MP and XP Plus protection levels offers significant protection to the IED threat described above.  Notable results can be concluded from this live fire evaluation. First, the armor kit withstood the blast wave maintaining its shape, form and its structural integrity.  Secondly, there was no fragmentation penetration to the crew compartment area.
