Assignment $2$: SRAW Test Data Analysis

Based on positive results in DT&E and following a successful Operational Test Readiness Review, the

SRAW entered IOT&E$.$ The IOT&E plan called for three phases with the first phase $(20$ shots$)$ being

focused on squad$-$level activities in a fixed$-$position defensive scenario. Results were mixed during this

first phase and after a Marine was injured while attempting to employ the SRAW, testing was suspended

until a safety investigation could be completed in order to address and$/$or mitigate any identified risks.

That investigation is on$-$going and testing has not yet resumed.

The Program Manager and Operational Test Director agreed to take advantage of this break in testing to

conduct an analysis of the IOT&E results to date. Your assignment is to analyze these test results

by answering the questions on page $4$ of this lesson.

Note that although this assignment and the Lesson $17$ assignment both deal with SRAW testing, the tests

in the two assignments are distinct. While the Lesson $17$ assignment covers DT&E on one aspect of the

SRAW, this assignment covers IOT&E and necessarily looks at the system as a whole.

Lastly, the Probability of Hit numbers provided on page $3$ predict how often the SRAW will hit the target

for a given number of shots aimed at that target $($assumes a successful launch$).$ In reality, the actual

Probability of Hit metric spans a continuum with the probabilities varying with, among other things, range

to the target, target maneuvering, and the use of countermeasures. The ranges and probabilities

provided are simply points on that continuum and are not meant to signify ranges that the SRAW should

or should not be used at $($the minimum and maximum engagement ranges do that$).$ As such, there is

no requirement to take shots at the ranges listed in the Probability of Hit row nor should there be$.$

analysis for grading, navigate to the Assignments section of the course $($outside of this

If you have other questions specific to this assignment, email TST$102$@dau.edu with your question$($s$)$; an instructor will respond as soon as possible.

$$ Question $1.$

o $($A$)$ Given the Threshold and Objective KPP values for the Engagement Envelope $($see the table on the previous page$)$ and noting that the results for shots $4$ and $9$ were essentially the same $($in both cases the motor functioned and the SRAW armed itself but both missed the target$),$ describe why not hitting the target on shot $4$ is different from not hitting the target on shot $9.$

o $($B$)$ Considering only shots $4$ and $9,$ which result $($if any$)$ is more problematic from a SRAW performance perspective and why?

$$ Question $2.$

o $($A$)$ When considering shot $4$ in isolation $($independent of the other shots$),$ does the result reflect an individual failure of the SRAW targeting system? Why or why not?

o $($B$)$ When considering shot $5$ in isolation $($independent of the other shots$),$ does the result reflect an individual failure of the SRAW targeting system? Why or why not?

$$ Question $3.$

o $($A$)$ Given that IOT&E examines mission effectiveness $($in this case, mission effectiveness equates to target destruction$)$ and assuming that target destruction occurs when a SRAW launches and arms successfully and then hits the target, note that neither shot $3$ nor shot $4$ destroyed the target. Are these two failures equivalent? Why or why not?

o $($B$)$ Considering only shots $3$ and $4,$ which result $($if any$)$ is more problematic from a SRAW performance perspective and why?

$$ Question $4.$ What one preliminary positive conclusion might an advocate of the system highlight? Make sure this conclusion is not simply an observation. Also, cite the data used to support the conclusion. As an example, an observation might be that the SRAW hit the target X of Y times. A conclusion might be that based on the results of shots a$,$ b$,$ c$,$ f$,$ g$,$ and j$,$ the system is on track to meet the Threshold Probability of Hit requirement for moving targets.

$$ Question $5.$ What one preliminary negative conclusion might a critic of the system highlight? Again, make sure this conclusion is not simply an observation and cite the data used to support the conclusion.
