The Iver4 PW UUV offers users a new 300-meter workhorse system featuring long duration capability and no shipping restrictions with L3 OceanServer’s Lithium-free standard design. The Iver4 comes standard with rechargeable NiMH battery packs supporting up to 20-hour run times of 40 nautical miles mission duration for long ingress/egress missions (40-hour run times of 80 nautical miles available with Li-Ion battery – payload and current dependent).

The Iver4 PW is the first in a family of advanced UUVs to address a wide variety of missions, including commercial and defense applications such as long range survey, multi-domain intelligence, surveillance and reconnaissance (ISR), anti-submarine warfare (ASW), seabed warfare and mine warfare. The new system offers survey customers a commercial platform that can be easily shipped on common carries without the concern of hazardous goods shipping.

The Iver4 PW comes standard with industry leading tracking and safety communications, precise and repeatable measurements, high accuracy navigation and low drag side scan and bathymetry transducers.
