I runga i te tikanga tuku-mate tuku iho, he maha nga tikanga whakapai ake kua whakawhanakehia, tae atu ki te mahinga mate kore-porous e whakaiti ana i nga hapa o te whakarewanga me te whakakore i te porosity. Kei te whakamahia te nuinga mo te tukatuka konutea, ka taea te whakaiti i te tukanga werohanga tika o te ururua ki te whakanui ake i te hua. He hangarau hou mo te whakarewanga mate tika i hangaia e General Dynamics me te whakarewanga mate ahua-totoka. I roto i te makanga kirikiri, te whakakoi o te waro waro iti he paparanga ma te paparanga, i te waro waro teitei he awhe pāmahana whakapatitioatanga whanui hei hanga i te whakakoi whakapiri.
