Attachment 1 – Rev A

DESCRIPTION & MISSION PROFILE:

PB-X will operate day or night, in all-weather and will patrol green water littoral zones such as coastal water approaches, bays, major rivers, ports, and harbors. Ambient conditions will range from 20° to 125°F ambient air temperatures (28°- 95°F water temperatures). Specifically, the craft will support maritime security operation missions and tasks such as Harbor Approach Defense; High Value Unit Transit Escort Operations; Visit, Board, Search, and Seizure (VBSS) Operations and Overwatch; Critical Infrastructure Protection; Amphibious Operations Support; Riverine Operations; Mine Warfare Support; Embarked Forces Support (e.g., SOF, EOD, USCG LEDET); and, Humanitarian Assistance/Disaster Relief (HA/DR) Support. The overall mission objective is "presence and deterrence.”

Boat crew rotation typically occurs 2 to 3 times during a 24 hour duty cycle period. Patrol missions are short transits of less than 1 hour, 25 nautical miles (NM) from base to the Operational Area (OPAREA). While patrolling an OPAREA a boat may be required to extend on-station time by loitering at very slow/idle to speeds of 5-8 knots and/or sprint at 35 knots to intercept a Contact of Interest (COI). Escort missions require the craft to match the speed of the High Value Unit which is usually between 15 to 20 knots.

Given the high annual number of operational hours on the water, a simple, reliable and easy to maintain design is highly desired. The high number of boats in inventory and annual operating hours, elevate the importance of Total Ownership Cost in this program. The Government is very interested in design approaches that: minimize fuel consumption; minimize systems and components; maximize scheduled maintenance intervals; have lower scheduled maintenance costs (labor and materials); leverage the Navy’s 3M program; provides commonality with other fielded systems; and minimize maintenance training for the end user. Two Total Ownership Cost (TOC) components of notable interest to the government are the Fuel Life Cycle costs and Engine Maintenance Life Cycle costs. Consideration is being given to use the metrics similar to those generated by TOC worksheets used by the government to estimate these cost. A sample of these TOC worksheets are provided (see Excel file "Engine TOC Workbook QSB6.7_420HP_6Oct16" and Word document "Engine TOC Workbook Instructions (4Oct16)". To assist Offerors in understanding these worksheets, sample data for an existing USN craft engine is provided. The sample data is NOT provided to indicate intent of desired engine selection. Feedback concerning the potential use of these worksheets and the metrics generated is of interest to the government and will assist in setting evaluation criteria in the Request for Proposal

The Navy desires a visually intimidating topside arrangement that will create a daunting presence and impression on all observers. PB-X will be easily and primarily identifiable as a military combatant craft and not as a standard harbor security boat or police boat.

· Heating Season. Capability to sustain crew space temperature of at least 65ºF dry bulb (DB). This requirement applies with ambient external conditions as low as 10º F DB and sea water temperature of 28º F, with full complement of crew and normal machinery operating.

· Cooling Season. Crew space shall be air conditioned to maintain as a maximum, 78º F DB and 65º F wet bulb (WB). This applies to external ambient conditions as high as 105º F DB and 87.5º F WB and sea water temperature of 95ºF, with full complement of crew and normal machinery operating.

Note: Thermal loading is an area of concern as a result the Government seeks solutions which take advantage of well thought out arrangements such as forward window cant to mitigate additional thermal loading associated with ballistic glass thermal magnification when exposed to direct sunlight.

Specifically, the craft will be launched and recovered; floated-on and off well-deck Amphibious type ships; or transported on a Roll-On/Roll-Off cargo ship with own trailer.

Road transportable also includes surfaces with loose gravel with washboard and potholes.

Capable of launch and recovery from a road transport trailer on a boat ramp.

In preparation for land, air, or sea transport the craft must allow for removal and stowage of fendering, masts, arches and platforms and weapons; transportation preparation should take less than 4 hours.

Threshold: 5 feet

US Navy Standards for single compartment flooding; and, US Navy Small Craft Beam winds and rolling; passenger crowding standards in accordance with NAVSEACOMBATSYSENGSTA Report No. 6660-99 REV.A: Procedures Manual For Stability Analysis of U.S. Navy Small Craft.

The vessel will be capable of conducting boarding operations on vessels up to 50 tons displacement with self-fendering, and be able to shoulder vessels up to 15 tons displacement without incurring significant damage.
