1.0 SCOPE

1.1 Identification
This document establishes the system requirements for the Shipboard Tow Tractor (STT).

1.2 System Overview
US Navy and Marine Corps aviation support activities have a need for the next generation of STTs to
replace the aging A/S32A-31B tow tractors presently in service. The STT's primary role is the handling of
aircraft weighing up to 74,500 lbs aboard the flight deck of naval ships. In addition to maneuvering
aircraft, the STT is required to provide a mobile platform and fuel source for the MSU-200NAV Mobile
jet engine air Start Unit (A/U47A-5), herein referred to as the MSU, and to extend cross deck pendant
cable during routine maintenance. To perform these requirements the STT must be a highly
maneuverable, compact, low profile design that is capable of an 11,200 lb draw bar pull (DBP).
1.3 Document Overview
This specification contains the requirements for the STT, which will be used to fulfill aircraft handling
requirements on flight decks of CV, CVN, LHA, LHD and LPD class ships. The STT will additionally be
compatible with the MSU, its L-frame platform, control panel, fuel and electrical requirements.
Section 3 of this specification documents the characteristics required for the STT. This section begins by
identifying the performance characteristics through functionality and corresponding performance
requirements. Next it identifies the objects with which this unit must interact, and the physical
connections, or links, used in that interaction. It then focuses on design constraints such as physical
characteristics, environmental, and design and construction.
Section 4 specifies the quality assurance provisions. This section lists the method to be used to verify
Section 3 requirements have been met.
NOTE: As part of the NAVAIR Systems Engineering process, this document was created using the
CORE® Software program. The Project Unique Identifiers (PUID) listed in each paragraph are inherent
to the CORE® software program and are a tracking mechanism used during document development.
PUIDs appear in this document in square brackets and are of the form [STT-FCN/ PI/ IF/ etc. - ####].
These identifiers are for reference only.

2.0 APPLICABLE DOCUMENTS

2.1 General
If a conflict exists between this specification and any other document specified herein, this specification
takes precedence. In those instances within this specification, where commercial and military
specifications and standards are indicated as "guidance only", the contractor is given latitude in
equipment selection, material selection, component selection, etc. This in no way relieves the contractor
from the responsibility of successfully, passing the performance tests in Section 4 of this specification.
Military specifications/standards and industry standards identified in this document establish minimum
performance requirements. Equivalent or better specifications and standards may be substituted upon
approval of the Navy. The Current Revision and most recent Notice of Change at contract award shall be
used unless otherwise stated.

4.1.37 Reliability Demonstration (RDEMO) [STT-VR-0039]
The Contractor shall use one or more the Pre-Production Units (PPUs) to demonstrate that the reliability
of the STT meets or exceeds the MTBF requirements presented in Section 3. The Reliability
Demonstration (RDEMO) shall consist of a minimum of 1,603 hours of cumulative, failure-free test time
during which the PPUs are performing within the operational profile described in paragraph b, below.


a. RDEMO Hours
Each unit included in the RDEMO must achieve a minimum number of hours of operation within the
operational profile prior to failure. The minimum number of hours required of each PPU prior to failure
depends on the total number of PPUs included in the RDEMO. The Contractor may determine the
number of PPUs to be included in the RDEMO. The required minimum number of creditable, failure-free
hours to be achieved by each unit included in the RDEMO is presented in the table below:
# PPUs       Minimum Hours per Unit                   Minimum Total Hours all Units
     1            1,603                                            1,603
     2               401                                           1,603
     3               268                                           1,603
     4               201                                           1,603
     5               161                                           1,603
Thus if, for example, the Contractor chooses to use two PPUs for the RDEMO:
      The total number of creditable, failure free hours of operation achieved by both PPUs must equal
or exceed 1,603 hours.
       Each PPU must achieve a minimum of 401 hours of operation prior to failure.
      The remaining 801 creditable hours required beyond the minimum number may be achieved in
any combination by either PPU included in the RDEMO (e.g., one PPU could achieve 402 hours and the
other could achieve 1,203 hours).
Creditable RDEMO hours shall be accrued on a ―clock-time‖ basis, at the rate of one hour accrued for
each one hour of operation within performance specification parameters and the operational profile. No
creditable test time shall be accrued for non-operating cooling down time, time spent conducting
scheduled maintenance, or for time spent with the STT running but not actively performing within the
operational profile. Creditable hours of operation shall be documented in Contractor’s format but shall
include, at minimum, the following data: date, operator name, description of operation performed (e.g.,
loaded transit and weight of load, obstacle type), start time, end time, and comments (e.g., performance
issues observed, maintenance performed, refueling/recharging, etc.).


b. Operational Profile
During the RDEMO, the PPUs shall achieve the minimum number of creditable hours in each operating
mode described in the table below. During these operating modes the STT shall negotiate obstacles and
perform tasks as described below.
Load               MSU Installed      Percentage of Creditable Hours
74,500 lbs         Yes                35%

24,000 lbs        Yes                  10%
                   No                   8%
No Load            Yes                  5%
                   No                   5%
Parking: The STT shall demonstrate the maneuverability and directional control required for spotting
aircraft by positioning a towed load in a designated parking area. This will be accomplished through an
equal number of parking cycles using of both front and rear pintles. A successful completion of one cycle
will include positioning and attaching the tractor to the towed load, pulling the load clear of the parking
area and to a position where both the tractor and towed load are perpendicular to the exit of the parking
area and then reversing the process and pushing the load back into the parking area and uncoupling from
the load. When pulling the load from the parking area the test shall involve an equal number of exits to
the left and to the right. The designated parking area shall be accessed from only one end and shall be no
more than four feet wider than the towed load (measured from outside edge of tires). Parking shall
account for not less than 10% of the creditable hours for each mode when towing a load. No parking task
is required for a no-load condition.
Ramps: The ramps(s) used during the RDEMO shall be set at a five degree angle. The PPU shall transit
up and down the ramp(s). Each ramp leg (up or down) shall be at least twice as long as the combined
length of the STT, towbar and towed load. Transiting up the ramp shall be performed at top speed for the
particular mode of operation, and that same speed shall be maintained downhill.
Stop/ Start Cycles: Stop and start the PPU's engine after each fourth ramp sequence.
Cables: The cables used during the RDEMO shall be 1-7/16‖ diameter cables and positioned
approximately 20 feet apart from each other. Transition of the cables shall be made at the top speed for
the particular mode of operation. Traversing the cables shall account for not less than 10% of the
creditable hours for each mode (load and no-load condition). The cables shall be laid across the direction
of travel at the following angles:
 90 degrees
 15 degrees
 30 degrees
 45 degrees
 60 degrees
120 degrees
135 degrees
150 degrees
165 degrees

c. Maintenance and Failure Events during the RDEMO




                                                 — 33 —
During the course of the RDEMO, scheduled maintenance must be performed as scheduled and properly
documented in Contractor’s format. Unscheduled maintenance shall only be performed as part of
corrective action after a failure has been evaluated and scored. Anticipation of failure shall not be
justification for preventive maintenance. Controls that are not accessible to the operator during normal
use may not be adjusted during the RDEMO.
If an event occurs that may constitute a failure (regardless of whether or not the Contractor considers the
failure relevant) notification to the Government and/or Government representatives must be made within
24 hours using the Failure Analysis Report. Barring threats to safety, the cause of the failure shall be
determined prior to disturbing the physical set up of the PPU, the test equipment, and any attachments.
NAVAIR will determine, in consultation with the Contractor, the relevance of the failure and the
appropriate failure category. If the failure is deemed non-relevant, this determination shall be
appropriately documented, corrective action shall be taken, and the RDEMO shall continue. If the failure
is deemed relevant, this determination shall be appropriately documented and corrective action shall be
taken. At the Contractor’s option, the PPU that experienced the failure may reenter the RDEMO with all
hours accrued on that PPU prior to failure discounted (i.e., the creditable hours of operation for the failed
PPU are reset to zero).
Failure to demonstrate compliance with primary function reliability requirements in a safe manner shall
be cause for rejection. The Government, and/or Government representatives, may witness any RDEMO
