Mitsubishi Heavy Industries' (MHI) aerospace arm has posted a 40.9% increase in its Q1 net sales to yen (Y)132.7 billion ($1.36 billion), compared with the same period a year ago.
This is attributed to an increase in sales related to commercial aircraft and defence, MHI says.
In the quarter, the manufacturer delivered 25 Boeing 777s and 16 Boeing 787s, compared with 21 and 11 respectively in the same period last year.
MHI has a 35% and 20% workshare on the 787 and 777 respectively.
Orders received during the quarter hit a value of Y92.6 billion, up from Y69.7 billion last year because of increases in orders related to commercial aircraft and space, despite a decline in defence work, says MHI.
Meanwhile, operating income rose to Y10.3 billion.
"Earnings rose significantly from a year ago as profitability improved in commercial aircraft mainly due to progress in the depreciation of yen," says MHI.
MHI's consolidated net income dipped 5.2% year on year to Y13.6 billion.
