REMUS 100
COMPACT SIZE & WEIGHT
• Compact size
and weight:
Weighing in at
only 80 lbs.,
REMUS allows
for economical
overnight
shipping and
ease of
deployment and
recovery.
REMUS 600, 1500, 3000
Greater Depth and Payload Capability
• 600 m depth
• 1500 m using
thicker body
• 3000 using
Titanium hull
• 600 lbs and 1012 ft.
• Up to 70 hours
depending on
speed and
payload.
