Manned Certification Evaluation of the Innerspace Systems (registered trademark) Megalodon Underwater Breathing Apparatus

Abstract

The Megalodon underwater breathing apparatus (UBA) was used in completing 99 man-dives. The primary test objective was to determine whether the UBA could control oxygen sufficiently to satisfy performance specifications published by Naval Surface Warfare Center Panama City (NSWC-PCD).The UBA failed in 4.9% of the 61 dives analyzed. One failure was due to PO2 overshoot duration greater than the allowed three minutes; two were due to regulation of post-overshoot PO2 >1.45. The UBA s performance adequately met the predetermined reject rule of <15% failure rate at 95% confidence. When used in conjunction with MK 16 MOD 1 dive tables, the Megalodon is deemed to meet NSWC-PCD performance specifications for N2-O2 dives up to 190 feet and He-O2 dives up to 300 feet. When diving, Megalodon users must maintain adequate training and familiarity with the apparatus.
