Sea-Air SystemsExpendable Oceanographic
Instrumentation

• Lockheed Martin Sippicans expendable probes
  collect data on physical properties of the ocean
  such as temperature, sound velocity and current
  velocity. The probes can be launched from
  aircraft, surface ships and submarines.
• Expendable Bathythermograph (XBT) The XBT
  provides an ocean temperature versus depth
  profile and is useful for anti-submarine warfare
  (ASW). Also available as a submarine launched
  version, the SSXBT.
• Expendable Sound Velocimeter (XSV) The XSV
  obtains accurate sound velocity profiles for the
  support of ASW operations, mine countermeasure
  operations, and oceanographic research. Also
  available as a submarine launched version, the
  SSXSV.
• Expendable Current Profiler (XCP) The XCP
  provides real-time profiles of current speed,
  direction, and temperature to depths of up to
  1500 meters. Also available as an airlaunched
  version, the AXCP.
• Expendable Conductivity Temperature and Depth
  Profiler (XCTD) The XCTD profiling system
  collects salinity profiles to depths of up to
  1850 meters. Also available as a submarine
  launched version, the SSXCTD and as an
  airlaunched version, the AXCTD.

Sea-Air Systems Data Acquisition Systems

• Military recorders are used aboard surface ships
  and submarines. The recorders display and stores
  plots of depth vs. temperature, depth vs. sound
  velocity, and /or depth vs. temperature and
  conductivity then output this data to an
  external combat system or work station.
• Commercial recorders are used aboard research
  vessels and ships of opportunity. The MK10A
  collects data from the expendable current
  profiler (XCP). The MK 10A receives the radio
  frequency output of the probe in real-time and
  converts the signal into digital format. The
  system processes the data and displays the
  readings of temperature and current velocity on
  the screen.
• The MK 21 Data Acquisition System runs on a
  laptop or personal computer using Microsoft
  Windows compatible software. Features include
  auto GPS input capability and improved
  post-processing options. The system is
  compatible with Lockheed Martin Sippican XBT,
  XSV, and XCTD probes.

• 1995 Production moved to Juarez, MX

XBT Production Facility
Production equipment, tooling, test stations and
all capital equipment moved to Juarez in 1995.
Process controls, inspection, sampling test and
verification processes remained the same and
include oversight from Marion support personnel.
14
XBT Production Facility
Copper wire winding process is tightly controlled
with a 100 verification to defined process
limits. Assures consistency and monitors
in-control process parameters.
XBT matching, thermistor leak tests and
continuity test stations are semi-automated and
have built-in mistake proofing. Process has not
been changed since earliest XBT production
approved in Marion.
15
XBT Production Stability

• Since the start of XBT production, there have
  been very few changes in physical configuration
  of the T-4, T-5, T-6, T-7, T-10 and DB family of
  probes. The next several slides will explain the
  changes and the measures taken to avoid any
  adverse effects in performance.
• Probe noses and plastic molded components are
  being made using the same tools and are supplied
  by the same suppliers as they were since the
  beginning of production.

XBT Production Stability

• Move to Juarez In 1995 the XBT production line
  was moved to Juarez, Mexico. All parts,
  processes, and equipment were sent to Mexico with
  the Marion line people to start up production.
  The Marion line supervisor remained in Mexico for
  over 2 years and has remained directly
  responsible for the line to this day. While the
  production staff did change in 1995 there were no
  product changes made at that time. In addition,
  the Marion QA team has continued to sample
  product from Mexico heavily and done visual
  inspections and at sea tests to confirm that
  probe reliability was not adversely affected.
  The following chart shows a summary of XBT QA
  results for reliability for the period preceding
  the move to Mexico up until today. Immediately
  after the move to Juarez the deepblue probe was
  re-qualified with NOAA with an at sea test (see
  next graph).

XBT Production Stability

• Wire coating change In 1996 LMS (then
  Sippican) was no longer allowed to apply the
  coating to the BT wire in house for environmental
  reasons. The same raw wire continued to be used
  but a new environmentally compliant coating
  process was developed and qualified. The new
  wire coating resulted in a change to the probes
  as built. The weight in air of the new coated
  wire was slightly lighter than the legacy wire
  and therefore the probe winding specifications
  were changed to account for the weight change,
  assuring that the wet weight of the probes and
  the weight per foot of wire deployed in water was
  unchanged from the baseline design.

19
XBT Production Stability

• Netting Added In 1999, in an effort to improve
  probe reliability related to the effects of
  shipping where the wire could be shifted due to
  shock and vibration, a light plastic netting was
  added over all wire spools that lightly holds the
  wire in place. Shipping, shock, and vibration
  testing demonstrated that this held wire spools
  in place better than the latex binder alone that
  was previously used on wire spools. The netting
  applies a very light tension to the top windings
  (a few grams) which diminishes as the wire pays
  out. Probes were tested in side by side, at sea,
  drops to demonstrate no measurable effect on the
  drop rate.

XBT Production Stability

• Recorder change While not related to XBT
  production there has been changes to recording
  systems used in support of XBT data collection.
  The original XBT users had analog recording
  systems. These were followed by the Sippican MK9
  recorder (HP based) in the 1980s, the MK12 PC
  based system was released in 1991, and the MK21
  PC based system replaced the MK12 in January of
  2000. Along the way there have been other,
  non-Sippican, systems used that have had
  performance issues and concerns. LMS has been
  careful to ensure that any system released

provides improved data collection accuracy while
not changing the basic launch detection
techniques. The MK12 and subsequent MK21 offer
the selection of the original equation or IGOSS.
The equation used is clearly shown in the raw
data file.
