According to the Pension Act, there is no difference in compensation whether you were in the navy or in the air force. It depends on the disability rate. If the widow's pension was reduced by 50%, it is because the veterans' pension did not reach 48%. If the pension is 48% and over, the widow's compensation remains the same. If the compensation is less than 48%, the widow receives 50% of the compensation.
