Hi John,

 

                A few comments:

 

Slide 11: “In schedule, all ADC QC tests will be complete by mid-2026”

                    The working schedule actually shows the completion in May 2027.  It is misleading to just mention the baseline schedule.

 

Slide 14: it would be nice to point to the picture where the LSB2s are, just like you did on slide 13 for ALFE and COLUTA

 

Slide 26: Under 6.4.3 BE Electronics

“Hold FEB2 FDR and launch preproduction”



“Hold STRM FDR and launch preproduction”

 

Slide 27: Last bullet. For PRRs it is probably better to say mid-2026, rather than early 2026.

 

Slide 30: “FY26 will see the completion of the scope in 6.4.1”.  See the comment on Slide 11.

 

                Tim should comment on the ADC QC test schedule in the working schedule. If it is true that the last ADC will be delivered in May 2027, it may get very close to the critical path.

 

                Best,

 

                Hong.
