   1.                                                   We note your revisions
disclosing an assumed price of USD$6.77 per Common Unit (with
                                                        each Pre-funded Unit to
be equal to the price per Common Unit minus USD$0.01). We
                                                        also note your
disclosure that the "actual public offering price per Common Unit and Pre-
                                                        funded Unit, as the
case may be, will not be determined by any particular formula but will
                                                        rather be determined
through negotiations between us and the underwriter at the time of
                                                        pricing." If you do not
expect the Common Units will be offered at USD$6.77 per unit,
                                                        please provide a bona
fide price range and revise your disclosures accordingly. Refer to
                                                        Item 1 of Form F-1 and
the instructions to Item 501(b)(3) of Regulation S-K.

2.       We note your response to prior comment 10 indicating that, with
respect to your MPSA
         agreement with GDMS, "KWESST is not dependent on the MPSA and the MPSA
is not
         material to KWESST's business or profitability." Your revised
disclosure on page 56
         states that this customer contributed nearly 64 percent of your
year-to-date revenue for
         fiscal 2022. Please refer to our prior comment and further clarify how
you determined
         that there are no agreements with your customers that are material.
With a view towards
         revised disclosure, if you do not believe the MPSA agreement is
material, please advise
         whether there are other agreements with GDMS that you view as material
given that this
         customer generated a majority of your recent revenue.

3.       We note you entered into a three-year contract with Counter-Crisis
Technology Inc.
         Please disclose the contract's termination provision. Tell us what
consideration you gave
         to filing a copy of this agreement as an exhibit to your registration
statement. Refer to
         Items 4.B.6. and 19 of Form 20-F.

4.     Your revised disclosure on page 3 indicates that you expect to begin
"commercializing"
       the single-shot PARA OPS device by the end of the fourth quarter of
fiscal 2022.
       However, you disclose on page 65 that the launch of your PARA OPS
business line is
       expected "during the third quarter of Fiscal 2022." Further, it appears
that you expect
       only the single-shot PARA OPS device to launch in fiscal 2022 (while the
multi-shot
       device will enter production in 2023), but you refer to the "anticipated
commercial launch
       of PARA OPS product line in the fourth quarter of Fiscal 2022" on page
56. Please
       clarify and revise to consistently refer to the production and
commercialization timeline
       for your PARA OPS product line. Further, refer to your disclosure on
page 47 showing a
       "pre-production phase" as part of the "estimate of the additional
investment to reach
       commercialization." Advise whether you consider a product in
"pre-production" or
       "outsourced production" to have reached "commercialization." Make any
appropriate

       updates to your chart on page 47, which shows that the singe-shot device

5.       We note your disclosure on page 51 that you "do not expect the ARWEN
product line to
         be material to our operations in Fiscal 2023 and thereafter following
the roll-out of PARA
         OPS and other anticipated military contracts." However, you disclose
on F-19 that over
         one-third of your revenues for the three months ended June 30, 2022
were generated by
         the ARWEN line and you disclose on page 68 that "ARWEN product sales
have
         contributed significantly to our YTD Fiscal 2022 revenues." Given this
significant
         revenue and the fact that your PARA OPS line has yet to reach
commercialization, please
         tell us why you believe you have a reasonable basis to conclude that
your ARWEN
         product line will not be material in fiscal 2023 and thereafter. For
guidance, see Item
         10(b) of Regulation S-K regarding disclosures accompanying
projections, disclosures of
         revenue without a measure of income, and the basis for projections.
